Possible to remove buttons from the main menu?

Specifically the updater and Entrenchment upgrade buttons. I've tried just straight removing them in the appropriate window files which results in a crash. Anybody done this successfully? I need the space for the rest of my UI and these buttons are superfluous.

edit: well, chalk this one to be the shortest time between thread and implementation ever, I tried removing them again and while the game threw an error it worked. so i guess just try it, it works!!!
