[All Your Pie]

That said, here's an idea that might capture the theme you want more simply:

Last Will
After revealing an Order Marker on the Honored Soulguides and instead of taking a turn with them, you may choose a previously destroyed Unique Hero in your army. Place that figure on any space adjacent to an Honored Soulguide and immediately take a turn with them. After that turn, destroy the chosen hero and one of your Honored Soulguides.

I personally don't know that I like it better than a simpler, cleaner direction, but if we want something a little more unique I think this works better than power copying.
