Spell request. Doppelganger

[.Blackheart.]

I was wondering if it's possible if anyone could make a spell called "Doppelganger". Not like the one from DotA All Star. This one will create an evil clone(Doppelganger) of the target(must be a hero). The clone will have the same abilites, stats, move speed, etc... And is invunarable until the original unit dies, I mean the clone will only die when the original hero die, until there he's invunarable.

Is this too much hard/impossible to be made?
Thanks in advanced.

Well you can always just use the targeted mirror image effect and make it target enemy heroes. But that leaves them without their casted abilities. But if you trigger it you will have problems with adding the abilities and it may mess with some hero death systems you got.

you mean that will be impossible to make the mirror have the spells of the original units?

i haven't done some tirggering in a while but i think you can get the unit type of the triggering unit so that you can easily make a copy of that unit.
