Very interesting variant. Looks like more modest variant of advanced wizard chess (but here air piece plays more importontant role) - http://www.chessvariants.org/large.dir/advancedwizardchess.html
What about subvariant, where land units can capture air units (for example, pawns captures pieces directly above)?
