n910t board in n910a frame Xpost from n910 board

Ok, so I'm looking to get a Note 4 that is capable of being modded. My friend is offering to sell me her n910a, but from what I understand it's not very mod friendly. What I'm wondering is if it's possible to just swap in a n910t board into a n910a frame. The only reasion I'm thinking of doing this is because her phone is mint.
Now, before you just say no, I've done a bit of homework and found that all the parts I looked up (LCD, audio assembly, camera) seem to be cross compatible. This makes me think it should just drop right in.

Anybody else have a main board failure? Here is my story.

Last week I was minding my own business, doing usual stuff on my phone and the device spontaneously rebooted into a bootloop at the Google logo. So I think "OK, no problem... I can try wiping cache/dalvik or at worst I have a recent nandroid backup" and proceed to reboot into recovery... except that it still hangs on the Google logo. Stuck at work I did a bunch of googling and found one other user who had the same thing happen recently.

When I got home I tried to fastboot flash TWRP again... but alas was still stuck at the Google logo. Next was a full flash of Google stock images, but that did nothing either... so I relocked the bootloader and had my provider (TELUS) send it in for warranty repair. I just had it returned with the repair stating the main board was replaced.

I have noticed a few users posting about being stuck on the Google logo and this concerns me a bit, as it almost seems like there may be some inherent hardware flaw causing the issue.

So I'm throwing the questions out there: Has anyone else had similar problems and is this something we should start to be concerned with?
