Strange. VBitSet is subclass of Vset.
May be bug of RB ?

You can try this 

  if bs1 <> nil then
     bs = bs.Union( (VSet) bs1 ) // Type mismatch error

    bs as VSet
    bs1 as VBitset


To coerce one of syntaxes (not remember which one in RB works)

    bs1 = VBitset( bs )
Or 
    bs1 = (Vbitset) bs
