Bigger brakes, in and of themselves, don't generally mean more stopping power (some argue that the larger rotor creates more leverage, but it is really negligible). Larger brakes are generally about increased thermal capacity, which means they can provide adequate stopping under prolonged usage, not necessarily a shorter stopping distance in an emergency stop.
Drum to disk conversion in the rear, again, is generally more about increased thermal capacity, as well as easier maintenance, but not necessarily more powerful brakes (and generally the rears can't provide more braking 'power' anyway as it would just be lost locking the tires as weight transfers forward)
Most stock brake systems are capable of locking the brakes, and if they are, going to larger, or multi-piston calipers isn't likely to solve your problem.
Stock rotors, and perhaps a more aggressive pad may achieve the feel you are looking for, or perhaps more power assist is needed?
But before making any changes, make sure the brake system is in good condition.
Is the pedal firm? Fully flush and bleed the brakes, and you may be surprised at the change..
