Please don't be foolish. If you want to play enhance near as optimum it's the hardest rotation following an UA Lock rotation. If I hit the keys the wrong way, I'll lose a quite margin of my DPS. I don't want to go into great detail.
I already played several DPS classes these days and they are fuckin easy compared with enhance. Even the Death Knight playstyle behaves like a facerolling wicked sick.
Honestly you can't be serious. Did you forget Elemental Devastation? Lava Burst would just change too many mechanics again.
