i have a pair of hs33 with evo2's on my old hardtail... but am only running 2.25 motoraptors.
hookworms are what, 2.5? i don't think it'll fit. i remembering reading somewhere that the evo2 adapters will accomodate up to a 2.4 tire, and even then it's going to be tight and your wheel is going to have to be pretty true to spin freely.
the evo2's do make the setup/adjustments a lot easier though.. if you can stand to go a little smaller (2.3 is probably pretty safe) i would definitely recommend them.
