Hi DVG,
Seems to me that satire often crosses boundaries, and in a good way. Since your purpose is to amuse the reader by playing against expectations, why not play with that in the query? "This is a work of satire, so even my characters don't know what genre they're within. I like to keep them off balance. One of them calls his world 'a superhero-franchise-satire, black-comedy-of-manners, with socio-political undertones, and an upper-class overlay of homoerotic camp'... if that helps."
That's just one approach and it might be terrible... but perhaps a starting point. I do like your mashup of Adams/Waugh/Marvel -- and from what I've seen, drawing such comparisons is a fairly standard tactic.
Good luck!
