Newbie rakeback question

I'm interested in Hollywood Poker's 1000% / $10k "superbonus", but only if I can also get a rakeback deal to go along with it, since it's 15x (rather slow to clear).

I've never had a rakeback arrangement before so this could be a very simple question. Can I get a rakeback deal somewhere without losing any of my bonus dollars - I believe "stackable" is the technical term. Thanks for any useful info in advance.
