Why do you way that?
How is the militia currently insufficiently regulated?
For one thing, the firearms that are to be used by the militia are not standardized. If we want them well regulated, everyone should be given the same type firearm, that was produced in a regulated manner.
Otherwise, you are stuck with a "somewhat haphazard militia".
If that's what you want, that's fine...but it would be unConstitutional.
Not necessarily true. Look at the state militia during the war between the states. The states militia in the north did not have standard weapons, some men carried smooth bore 69 cal muskets at the beginning of the war. While others carried rifled bore rifles.
Evidence that the war between the states was un-Constitutional. It was not fought with well regulated militia, therefore the entire thing was illegal.
