Here's one that I've been thinking of for a long time, but keep forgetting to
post:
A special blob-CSG used in blob statements. You should be able to do unions,
differences and intersections all within the blob statement. This would be a lot
more versatile than the current negative blobs. The result would be something
like a rounded version of a CSG of spheres and cylinders.

Currently you can't really put a blobs sphere in a place that has a larger
negative blob without drastically changing values, making it very difficult to
work in areas that contain negative blobs.

It would probably look something like this:

blob{ difference{    sphere{<-1,-1,-1>,2,1}
                                intersection{ sphere{<0,0,0>,1,1}

                                                    cylinder{<-1,-1,-1>,1,.5,1 }
                                                    }
                             }
        }

I'm sure this should be possible - I just don't know if it would be just as slow
as isosurfaces in which case it would probably be redundant.
