are these ever grafted on to different root stocks?

?? They are normally encouraged to throw new shoots from
the roots by planting very deep and by pruning at least some
shoots down to ground level each year. Grafting onto a different
rootstock would make life very difficult.

By the way, what variety of blackcurrant are you classing as
'sweet'? I have, I admit, a sweet tooth, so maybe my opinion
doesn't count- but I've never tasted a sweet blackcurrant yet.
