Why go small cat? Checkout the vicious link. Sparky Olsen builds a very high quality vacum bagged 31 that would fit your needs and probably budget too. Plus he's been talking of smoothing out the lines in the mold to give you more of the look you mentioned. Would be a runner that's for sure.
Heck slap in some quality small blocks and completely please your insurance company. I can help ya there too! Would love to see a set of LSX based marine engine s/b in a offshore cat
