That is very true. This would best happen if the level of government above the elections in question requires they all work the same way. For example, https://en.wikipedia.org/wiki/Fair_Representation_Act_(Unite... would require that all the house districts go SVT PR at once. Likewise, a state could reform all their state legislature districts at once.

I can't wave any magic wand for gridlock at that level, but that bypasses the coordination failure by not requiring coordinated steps at all.
