Growing persimmon trees in pots -- DV rootstock

It appears that I now have too many persimmon trees and not enough room! Some trees are in pots and will never go in ground.
These trees are all on northern virginiana rootstock and growing! Is it possible to keep them in pots indefinitely with root pruning?
Since DV has a long tap root and supposedly less fibrous growth, was it a mistake to graft to DV in the first place? Is lotus a better rootstock for potted culture?
