Tomato - multiple root stocks?

[Duronal]

After reading an article about grafting tomatoes i was wondering whether you could graft more than one root stock onto a tomato plant? I guess you'd essentially be providing a secondary root stock which would increase nutrient intake and may in turn increase growth.

What do people think?

In the same vein I was wondering if there are dwarfing tomato root stocks that could be grafted onto something like Gardeners Delight ?

Anyone ?
