All of the guys from ZONE and Battle Stars have "Base Modes" with the ramps in question.
No pix at the moment, I'll have to work on it later.
For ZONE, Dia Atlas, Sonic Bomber, and Roadfire combine together to for Big Powered, however, each has it's own base mode. DA comes w/2 ramps and SB and RF don't have ramps, just some "Cracked" out base modes. All come with Micromasters.
In Battlestars, you have Star Convoy, Grandus, and Sky Garry. Each comes with at least one ramp and all come with a Micromaster.
Other than that, I think you have named all of the MM bases.

*edit*
This may help.
