Change static mesh of single instance of PCG (HISM)?

I use a PCG spawn to give me hundreds of trees.

When the player touches a tree, I’d like the tree to change static mesh (so it goes from a living tree with leaves, to a dead tree)

Is it possible for me to change the static mesh used for just one such PCG instance at runtime like this?

I could of course spawn a new blueprint and move the dead tree to the instance’s location, but this feels like it would lose some of the performance benefit of PCG.
