Any color keyboard mods for 920t

I haven't seen any flashable keyboard color mods for the s6 or specifically for tmobile variant. .There were quite a few in a short amount of time for the s5.
Any links, or direction toward this would be great unless there just isn't any available. Not talking about keyboard apps, just retaining stock keyboard with color option

T-Moble 920T SIM Unlocking and keeping WiFi Calling and VoLTE (Can it be done?)

Guys, I have a question for anyone that's SIM unlocked their 920T's. At the moment, my 920T is running xtresolite 2.2. It's based off a 920F firmware. As you know, this is an International version. To further complicate things, I needed to SIM unlock my phone so right now I'm using the MetroPCS COF9 baseband. Every time I switch back to a T-Mobile based ROM, my SIM unlock gets pulled and the phone is relocked back to T-Mobile (has been confirmed in multiple posts on XDA). I'd just stay with xtresolite 2.2 but I have no wifi calling or volte. I'm trying to find a rom for this phone that supports a different carrier sim as well as volte/wifi calling when I switch back to my T-Mobile sim. Is this possible?

All the ROM's I find for the 920T are either locked down T-Mobile ROM's under that development section and the general development section is mostly compatible International variants - but lacking WiFi calling or VoLTE. I'm beginning to think these two things just can't work together on the same ROM.

Thanks so much in advanced for a reply!
