Warhol is painful to me - I hear "whore" hiding in it. And it might be difficult for the child if you give him such a well-known name but with an obscure, non-standard namesake, even as a middle name.
If you really want a Bowie-related middle name, why not
Jareth? I know it sounds really trendy, but it's 100% Bowie.
