Here's another set of Lego Ideas submissions that I think the MFZ community should take a look at.
Exo-MicroForce. A pair of micronized Exo-Force mechs that just so happen to be at 6P scale. The designer is a member of the Hangar.
Hardsuit Kit. It's designed to be a "Hardsuit" at minifig scale but, if you change the head it could be used at 7P scale for MFZ.
Tesla Troops. This is by Garry_rocks, I've done a Spotlight post on his work.
Chronos. This was inspired by MFZ. He's also a member of the Hangar.
I've supported all of these submissions.
