Rezzerecting a hero?

Is there a way to make a spell whre you can rezzerect a friendly hero? i want to use it for an RPG im working on. Like ther hero will only be able to be rezzed after one minute?

mmmm no because there is no body to ressurect...i think so anyway

When the hero dies, create a point or region where the hero has died. Then make a trigger where if the unit begins casting the ability "Resurrection". Then do an If then else and if the hero is within 600 of the point/region, then revive blah hero.

What i was thinking is make a dummy spell, like Roar maybe, and then if the spell is cast and there is a "point" within that area the hero would be revived. u jsut didnt know what to use as a temp for the hero's corpse, thanks!
