Default Cross ROM Flashing

I am trying to find solid answers on this before I do it, but can't find any evidence it will work, and without issue. I just want to gain my T-Mobile wifi calling, and be able to use IPv6, but the ROM that my Note 3 came with, does not allow any of this (APN protocol is perma-greyed out and of course no wifi calling).

So here's what I have: Mexican N900W8

The ROM I want to flash: N900T for T-Mobile. Stock ROM.

Can I just simply use Odin and just flash it without rooting or anything since both are stock ROMs? Or do I still need to root it?

Also, if it will just flash right over, will my phone identify itself as a N900T and get over the air updates for T-Mobile, or will it ID itself as a N900W8 still, and possibly have future update problems?

Lastly, will all the other hardware work fine without issue? Wifi (most important obviously), NFC, etc?

Thanks.

I tried looking for this kind of cross flash but could not find anything whatsoever concrete that re-assures me this will work.

I would really like an answer for this.

Can I cross flash a stock ROM or not, and in this case N900T to N900W8 without any wifi issues?

You can flash 900T ROMS on the W8, however, not via Odin. Has to be done via Custom Recovery and you still have to flash the W8 kernel for it to work. - Essentially yes, You have to root, but I don't think you can get your T-Mobile WiFi calling unless you have an actual N900T.

As radical said, you can flash it using custom recovery.

It will show up as N900T instead of N900W8, but you can change this using "build prop editor" from the Play Store.

You will not get any OTA from T-mobile, custom ROMs don't get official OTAs.
Problem with ROM? Try this or ask me on G+!
Root/TWRP/Kernel/ROM and KNOX 0x0 on N900W8? My guide.
