Is it futile to try use a donor display?

So, I naïevely purchased a cheap-as-chips A2485 mbp with the logic board removed, with a view to buying a cheap identical mbp with a cracked screen, to make one working fantabulously cheap mbp.

Subsequently reading this MacBook Pro 16" 2021 Screen Replacement, I came to think: great! My plan should work! If there's a guide for this, and iFixit sells the parts (on rare occasion, when they come up), then surely this is a viable solution 🙂

However... I've since stumbled across this post Display issues on MacBook Pro 14" M1 - Shadows on Screen

The updated first answer gives me a strong impression that any attempt to replace the display with a donor (not sourced directly from apple) would essentially be futile, due to the apparent need for system calibration to pair it to it's body.

There is a caveat in that second post, insofar as desoldering a couple of specific ICs and transplanting them onto the new display should get around the apple calibration/serialisation issue. However, I attempted to shop around little ol' New Zealand to find someone to do such a repair, found a repairer who works with someone who apparently has the full schematics for this model of mbp, and has experience with this sort of repair, and this is the response I got from them when asking if they'd do it:

"this type of job is beyond their capabilities. It’s mainly due to the schematics of the board, security that Apple puts on its logic boards & the complexity of it (High risk of it not working) & they don’t think it would be a successful job"

So, back to my original question: is it an exercise in futility trying to use a donor display assembly (that is not sourced directly from apple) to replace the display of a broken A2385 mbp?

Or is there some solution to my goal here that I haven't thought of (aside from getting a new logic board from apple instead)?

Thanks for any and all help!!

Currently, I have in my possession a 16" 2021 M1 Macbook pro A2485, which I *think* is missing the logic board only (bought of trademe (NZ eBay equivalent))

I want a functional 16" 2021 Macbook pro A2485

I believe the cheapest solution is for me to purchase an identical model (A2485) MBP with a broken display, and have my current display assembly, which I believe is perfectly functional, transplanted into an otherwise perfectly functional MBP with a broken/malfunctioning screen. I currently have my eye on a A2485 with the auction closing in a few days, to enable this - *if* I can get a repair combining the two, to actually work

Alternatively, I believe another solution would be to have a matching, functioning logic board with paired touch ID transplanted into my current MacBook shell, such as this one MacBook Pro 16" (2021 A2485 M1 Pro) 10-Core CPU/16-Core GPU Logic Board with Paired Touch ID Sensor . I am under the impression that this will be more expensive (I do not have the liquid-damaged logic board to exchange through apple's self-service program), but obviously that depends on how much a A2485 MBP with broken display ends up costing me, so that may not necessarily be the case

So as far as I can tell, my options are as follows:

Option 1: attempt possibly futile display assembly transplant from Mac with no logic board to Mac with broken screen

- Find ways from iFixit big brains to make this less likely to be futile 🙏 🤞

Option 2: buy logic board with paired touch sensor to transplant into my current Mac with no logic board. Hope that iFixit big brains tell me if this is a dumb idea/ how I can make it work without it likely going 🍐-shaped

Option 3: %#*@ it all to hell, throw the beautiful MacBook I have in the trash/ on a $1 reserve auction for some poor soul to go down the same rabbit hole/ dead end as me

A final note/ question on Option 1:

Is it somehow possibly to do something like do display transplant without T-CON transplant, and also intentionally break something isolated like a lid angle sensor, then go to an authorised apple repairer to have intentionally broken sensor repaired, and then in the system calibration post-repair, apple inadvertently fixes the display serialisation/ non-matching T-CON?

I'm probably showing just how naïeve I am with the above suggestion - maybe the lid angle sensor is a dumb example and there's a better part to try that on with, maybe the authorised repairer will notice a display mis-match when attempting the repair and refuse service, maybe the system calibration post- authorised repair will only work for said repaired part, or maybe apple will pick up the non-apple-sourced display on calibration and not complete it. I dunno. But figured it's worth throwing out there! Thoughts?

Or any other suggestions for me avoiding going nuclear on option 3? Thanks!!
