Problem is, blobs just don't work that way. They are isosurfaces of the 
sum of all the components in a blob...there would be ambiguities in 
trying to figure out which blobs should affect a point. (blobs don't use 
the isosurface solving algorithm, they use a more specialized algorithm 
instead, but I don't think that helps any)

For maximum flexibility, you need some kind of surface-based shape, like 
a mesh, spline patch, subdivision surface, etc...with these, the surface 
can fold against itself, or even go through itself, which is just 
impossible with a single blob.
