Two pounds of honey malt is way too much for my tastes, but to each his own. Personally, I'd use no more than a half pound of honey malt. You'll still get the honey element without it completely dominating. Keep the wheat, but drop it down to a pound and throw a half pound of crystal or munich in for some more complexity.
75% efficiency isn't poor, IMO. I have always felt that it's better to know your efficiency rather than worry about how high it is. Work with what your equipment gives you and build accordingly. Nice thing about homebrewing is that it won't break the bank to add a few ozs or lbs here and there.
I'd go with Cascade all the way through.
Not trying to be critical in any way with your creativity. I'm a 'less is more' guy.
Good luck.
