I'm fine with having this RP be Zeta era.  I'm mostly familiar with the One Year War and Unicorn bits of the Universal Century, but I have also seen Iron Blooded Orphans, Seed, AGE, half of 00, and I do intend to watch Wing and Witch from Mercury. When it comes to the suits mentioned I think those would be good to start with. I'm down with the idea of starting with grunt suits, and the maybe have Gundams later. Or we could keep it grunt suits only to maybe have a grittier take on the Gryps Conflict. I don't know, that's just my idea.
