The Grey Sword/Garuru Cannon parts for Omegamon in particular really feel like they should have been (the bottom of the arm parts are removable anyway) and I kinda wish they'd tried to figure out something for Angewomon's bow and Lilymon's cannon. Would also have preferred Zudomon's hammer being done this way, if it had to, instead of it just being molded into his hand permanently, desu.
Anyway, I really do think it's likely for volume 4, since it'd round out the set to 3 like previous ones, and it really probably wouldn't be that hard.
