Yeah, the interface images supplied by beleg would be great. Perhaps the only two things I'd suggest would be
1. a constant mini health bar across each minion icon, so you could at least keep tabs on all minions health at a glance rather than having to cycle each one to check health
2. Specific minion icons for each minion class, So I can tell where my bone minions are to cast death nova on, and where my flesh golem is for smitebombs, ect
I can't speak for everyone, but myself I play as zoomed out as possible so I can see as much of the battle as I can, and though the itty bitty health bars above the minions are better than nothing... trying to squint to see the health of your minions thru moving players and mobs makes my eyes bleed sometime... ok a lot. Then there's the fun of trying to select a minion in a battle... There would probably be less cookie cutter MM builds if it was made easier to manage minions.
