There were some and there are at least a couple that have been developed, but never put into production. VW went down this path with the Vanagon. The productiion numbers were never high enough to make them attractive to the HBA crowd.
I'd skip the air-cooled and go straight to liquid cooled, but then we run into the chicken/egg thing. There just aren't any airframes available that were designed for liquid cooled engines in this Hp range. Trying to stuff the radiators in the cowl or under the belly in a plane designed for an air-cooled engine has been proven to be far more problematic than adapting one air-cooled engine to an airframe designed for another air-cooled engine.
