Make slaves use mouseover-target from main?

No.

Aha! There actually is a way. I don't know if this is exactly the functionality that this guy wants, because ultimately the minions are assisting off of the mouseover.

Go into WoW keybinds->targeting scroll down to Interact with Target. Right above, or below (forget) is "Interact with Mouseover"

Create a keybind, step 1, have it do an assistme action, and a keystroke action that outputs the key you bound with "interact with mousover". This will cause ALL of your minions to assist off of your mouseover and target whatever you've moused over.

If you want your minions to also actually move, then you can add the interact with target actions in step 2.

I've got a macro just like this for looting, so that I can just mouseover and loot rather than click bodies then IWT to loot.

For casters, like his mages, I imagine he'd want to use the face target IWT option in step 2, so his mages will turn to IWT with the target, while getting their assist off of the mouse over.

... no, they are assisting off of your selected Target, that's what "have it do an assistme action" is doing. Your toons cannot determine your mouseover. WoW does not share your mouseover with other clients.

Right, hence the "not exactly" the functionality, but it is fundamentally achieving a mouse over system.

You mouse over, hit your hotkey, they assist and cast/attack without you having to manually target.

Throw a target last target output, and voila.

Yeah, that is (and goes back to) what Wizeowel said.
