Does anyone know of a good headswap that might work for the Target/Keaton/Toybiz Vintage Batman figure? I love this figure, but I really don't care for the headsculpt...I appreciate the look but I feel it's a bit large. I've tried looking for casted head to paint myself, but that's gone nowhere.

I've thought of using one from the basic Mission series figures, but I've seen pics of the swap, and those seem a bit small on the Multiverse body. I've also been curious if one of the Mezco Heads would work on it (in particular, the Sovereign Knight head.) Any suggestions would be great!
