Generic Warboss unit leaders

Wot do u gitz fink of having sum generic warbosses to go with da ladz dat don't have leaders? Warbosses that can strap sum rokkits to der back to lead stormboyz or a good ol dakka warboss for the more shooty boyz?

Non ork speak how would you take a warboss that could be equipped (same sprue) to lead different types of units in the place of our old epic heroes that used to lead them?
