You’ve got some moderately highbrow and transhumanist stuff in there; have you tried Greg Egan? The two starting places I like to recommend are the Clockwork Rocket books (natives of a universe with alternate physics explore it and figure out what’s going on, kind of Flatland turned up to 11… and then up to 121…), and Permutation City which I think will meet your “some very interesting ideas” and then keep accelerating.
