If the "g" you mention is G forces for yanking and banking, you'd want to be much faster than Vmca. Vmca gives no stall protection, it's only for directional control.
If you're going to yank and bank, you need to be at min maneuvering speed for the configuration (and then some). At least 1.3 Vs for the configuration, and even then you'd better be gentle.
