The links I provided (here and here) confirm they are indeed the characters of Earth-71912. The A-Babies vs. X-Babies one-shot and the Giant-Size Little Marvel: AVX limited series are nothing more than expansions of the Baby Variants. Their case is similar to Gwenpool's.

The LEGO Variants were launched to tie-in to the launch of the LEGO Marvel Super Heroes video game (here).
