Sure. Here is a motor mount and servo tray to go from 2 to 1 servos:

And once you decide what battery you will use, you can check the dimensions and Mike here at rc-monster will make you a custom battery tray.
Is it a 2 speed? Ofna makes a 51 tooth single speed spool, or ultra center diffs fit if you want diff action.
Did I miss anything?
