Well, one thing you have to keep in mind is that KR isn't afraid to use characters in suit only. While it would be wonderful to actually get the characters to reprise the roles, it's a rather well known fact that Odagiri doesn't want to come back (Granted, it's been 20 years. Maybe he's had a change of heart?)

Anyway, another question. What's the point of Best Matches in Build? When I first saw Hawk Gattling, I could immediately see the benefit what with the homing hawk bullets. However, no other Best Match has any real synergy.
Panda Rocket doesn't offer anything any other claw/pointy weapon could use with Rocket. Hell, Porcupine is objectively better since it's points can extend at will.
Nin Nin Comic has a special sword, but Build had to design and build that sword after he found out about the Best Match. So, without the sword, what makes that combo worth using? Same goes for Pirate Train and it's bow.

I really wished Best Matches were akin to OOO or Double combos, where the "Special" combos offered unique abilities that only said combo could achieve, like GataKiriBa's cloning or LunaTrigger's curving bullets...
