Looks like it's a two speed, gears << BIG problem >> a motor mount and a short lipo, you may be good. A LOT depends on your skills in part blending.
Like ThePanda posted would be hard to do.
Did the conversion to a GT, GT2 and SC10GT. The big problem was making a motor mount, AE already had the gearing bits, just change from 32 to 48 pitch spur and pinions AND they were 2wd.
