Yahtzee, your game has already been made. Twice. There aren't mercenaries but the action players can still muck around doing what they want. In short you really should check out (or even just check a youtube video of) Battlestations Midway and Pacific to see that RTS and 3rd person action can coexist, at the same time, and extremely well, too. It's actually kind of embarrassing seeing you go on about this idea of yours when even I knew it's been out for years...
Personally I cannot stand RTSes either, to me they'd be more interesting if the computer did everything for both sides and the whole affair was turned into an entertaining screensaver. That said, I did actually get pulled into Company of Heroes. A well told story tied to gameplay so extensively play tested and refined that I just couldn't find anything wrong with it.
