You could switch to pusher fans and that might get you enough room. Another hurdle is the LS9 snout will have the throttle body in the radiator as well. I don't know if the LSA snout is similar enough to swap onto the LS9, but that is what you would need. You would still have all the HEX, lines, and pump fab work to do as well.
I hate to say it, but I would go with an E-Force like myself, Cutter05, and Jeywar have done. It uses the accessory belt so you don't have to change everything over to the dedicated drive belt setup. All you can use is the E-force head unit, fuel rails, and LS2 belt tensioner kit. Everything else is harder to adapt to our cars than sourcing separately.
If you're bound and determined to use an OE blower, I would use the V2 LSA blower vice an LS9 since you can get one used (much more plentiful and much less $$$) and that would alleviate some of the intake tract issue's. The LSA unit will get you everything you are looking for and more.
If you have the cash and the time I would like to see the outcome as well though!
