You're right, packaging would definitely be a challenge. The cylinder head would need to be low profile, conformal exhaust headers, dry sumped, and put all the plumbing you can (including the turbo and wastegate) behind the block. Maybe it’s not feasible, but it sure would be an interesting puzzle to try!

The peeps I've talked to who've done LS swaps seemed more interested in the economic, technological, and fuel economy leaps made versus the certified air-cooled default choices rather than the power, but YMMV...
