I don't see the "either side can move first" as being particularly noteworthy. You've eliminated the white/black advantage, but the first/second player advantage isn't changed.
Personally, this seems to just be a decimal subvariant of Fergus's Gross Chess; the rule adjustments seem to just be conforming to the smaller board. The further piece reduction to your other game (in particular using the Leo in place of the Pao and Vao) seems a more separate variant (while still clearly inspired by Gross, with the compounds and Omega pieces and hopper[s]).
