The cooling can be improved by making the fins larger to crate more surface.

If just for you, why not? Would be fun. I've built some small engines. If to resell, well, that's a whole 'nuther kettle of fish. Nobody wants to be first to find out something didn't work as expected and lawyers and insurance along with that safety conservativism is why airplane parts cost what they do.
