So in essence, aside from differences in dimensions, pencil 2 carts are coleco carts correct?

Right, which is why there was a cartridge converter.

I see. Speaking of which, I'm curious regarding the innards of said converter.

It shouldn't have any innards from what plg said. It's purely making the connections work.

I thought the bios was different and incompatible? assuming cart space can completely override system space, I guess it contains a compatible bios?

The ColecoVision carts insert perfectly in the main slot.

[EDIT] guess there is a CV compatible bios and some glue chips and thats it in the adapter

I'm confident I can just hook up a 27128+switch and have the bios change from one to the other.

Just tried one game. Surely the switch from 1KiB to 2KiB of RAM will cause issues to some game assuming mirroring. I'll try a few more later.
