Yes,that's why I'm looking for alternative scions,and this is only a guess,but I think herbacious perennial solanum species are the best candidates because they already store energy in their roots just like potato,so for them it would't be a problem to split energy for both tubers and their fruit(which is also kinda required,because you'd need the seeds of the scion for next year's grafts).
As for tomatoes,they aren't bad "tuber pumpers" but only when not allowed to spend energy on flowers and fruit.I'm also considering other more distantly related plants within solanaceae,it might be possible.
