I know in bonsai, to create a new leader you take the strongest shoot (from those resulting from the break in the leader) and wire it upward and prune off all other nearby shoots so that all the energy goes into that one shoot. I'm sure the same principle would work with a normal size tree accept you might straighten it out by strapping a plant stake to it like a splint instead of using wire.

Just position the shoot so that it goes in the same direction as the old leader and secure it with the stake and ties. Of course, make sure you don't break that one in the process. Then after the shoot has hardened you can take off the stake. It should work, but I'm basing this on my knowledge of bosai and I don't know anything about Tulipwood. Hope this helps : )
