i believe renaming will be in, and name lists can already alter the names of your ground huggers.
one thing i personally am looking forward to in a future DLC is some kind of army template designer on the customisation side. As it is, i think you have to manually go through each army to add something like Power Armor or combat stims. I think treating them kind of like modules and training a template which you set to have anything from nothing (vanilla) to power armor wearing troops with terminator infiltrators (end game kind of stuff) would be lovely and a lot less clicking
add that and i think army customisation will be absolutely solid
