So since I brought up Roboriders anyway, I'd like to do some brainstorming on the topic. The first hurdle I'm undecided on is exactly what sort of form it would take. I basically have three ideas on that:
>more or less just a motorcycle with only the more basic anthropomorphic elements that the original sets have
This would be the least Bioniclesque option, basically, which would either use masks for the faces or their original heads (or more greebly part-built approximations).
>motorcycletaurs, motorcycles with partial torso and arms
This I feel is probably more in the spirit of the originals, since while they're obviously motorcycle-shaped they have clear heads, arms to varying degrees, and in some cases like Lava or Swamp something approximating a torso rather than just a chassis.
>straight-up Toa adaptations
Boring, but more straightforward. I would probably make them the rest of the Chronicler's Company since the colour schemes actually line up pretty well. Obviously using those colour schemes preferentially where they conflict with the CC and with weapons based on the Roboriders'. Macku would be replaced with a new member of the team since she's off in space being a Slizer.
The second and arguably bigger hurdle is how to integrate the wheel-launching function, since like with the Slizers I think it's an important part of the whole concept. With either the motorcycle or 'taur options I can't use them as wheels the same way, since scaling it up means the actual wheels have to be larger more conventional Technic wheels. The launchers would have to probably mounted next to the front wheel without ruining the profile of it all (maybe folding out?) or possibly over it. If I go straight Toa, it's even harder, since while the launcher assemblage can be mounted easily to a socket piece it looks a bit shit (see the Power/Onyx humanoid combiner). I'm thinking in that case probably over the shoulder as with a few of my Slizer mocs.
So, thoughts? There are no dumb ideas.
