How much Kitbash Bits in Scarab Terminator Box

Hey watsup guys I built 5 terminators with a soulreaper cannon and a sorceror. I want to buy another box to make a ten brick of scarab terms but i was wondering is there enough bits to replace my soulreaper cannon guy arm with the gun and also build 5 regular terminators because I already have my 1 sorceror for the brick and I messed up when I built his cannon.
