I like the idea, even if I don't know a thing about balancing or design and can't tell if it'd work in a realistic setting.

Too bad SE won't ever change SMN because, let's face it, that's a shit ton of work to put into a single job that still outperforms most others by a mile. Not to mention all the people who'd be pissed that their main class was changed so drastically that they'd have to learn an entirely new rotation, breaking muscle memory that has been built for almost three full expansions by this point.
