Why would you do that? Verizon phone's are SIM-unlocked, just popping the T-Mobile SIM should have sufficed IF the network radios are supported (I know the S8 can, and I believe the S7 also can, but I'm not sure). T-Mobile's and Verizon's had different hardware, so flashing different ROMs is certainly going to mess some things up.

T mobile may not support WiFi calling

All us s7's are the same hardware wise. Also as soon as you insert a Sim in a s7 it locks to that carrier. If I'm not mistaken t mobile doesn't support wifi calling. Not all carriers support it.

T-Mobile does support WiFi calling. IIRC it was actually the first carrier to activate it either on the S7 or the Note 5 line.

Also, not entirely sure the hardware is the same exact one. They ARE listed as different models, and at least in network support, all carrier models had distinct differences.
