Have you tried a long lever and the trick of bolting the remover tool onto the end of spindle (on the cupside you want to remove ) which stops it slipping. Wrap the BB cup and frame in a little bag or cling film to create a little pocket and fill it wd40 or plus gas so that the cup is submerged then let it soak.
