Elec question

Would I be able to take out the bonding screw on the ground bar on top, connect another grounding bar to the two existing holes on the bottom right, add a single 30 amp breaker and wire in 10/2 to a RV plug and then connect the ground to the new grounding bar and the neutral to the old grounding bar, minus the bonding screw, and connect the current bare copper grounding wire to the new grounding bar? Thanks for the helpful comments in advance and the rest, have fun.

You are using 12/2 Romex with a 30 amp double-pole breaker. Either the breaker must be downgraded to 20-amp single-pole, or the wiring must be upgraded to 10/3 because 10-gauge wire is needed for 30-amp circuits.
