I did #3 before, since it seemed the only quick and easy way.  I only used a
copy of the body and CSG differenced parts from it and scaled up slightly,
exactly what you are thinking.  Turned out that scaling a blob is like
scaling a sphere that has already been placed in a location, which is to say
it all moves as well as resizes.  I ended up compromising scale and an added
translation to sort of fit the shirt to the body.
If you intend to animate the thing, and I know you are, it'll be heck to
deal with because I also did that too.
