Default [Q] Easiest way to "clone" two HTC Ones?

Hi all, I'm switching from Verizon to T-Mobile. After hours of searching, bricking, then recovering my HTC One (don't try flashing a T-Mobile radio to a VZW phone...) I've come to the conclusion I need to buy a T-Mobile HTC One.

I have my device set up the way I like it, with custom launcher, the way things are arranged, etc. Is there an easy way to clone my Verizon One to the T-Mobile One I eventually buy? Without having to reinstall everything and reconfigure all the settings? Thanks.
