I know the effect could somewhat be done just using sparser graphics (No hero battle sprites, no projectile attacks, minimal attack graphics) But there would still be issues with the placement of the battle menu (in the upper right by default) as well as the cursor above the hero sprite. (maybe it be removed, or changed to blend in with the background?)
Anyway, like I said, I'm not planning on doing a game in that style at the moent, I was just curious.
