The LEGO thing could just be that when she's in the LEGO Marvel universe, her physiology changes to fit in that world because everyone has to be a LEGO. It's like when the Living Laser of the Ultimate Spider-Man cartoon gets transported to the Super Hero Squad reality and his appearance is changed to match the SHS.

Her future counterpart could be similar to how Merlin has a future counterpart, though Merlin's appearances have always been confusing.

As for AA, I really don't know anything about that. Don't know if it will ever be explained canonically.
