External clamps taking less than 1/20 are of course allowed under Smaller Systems. But they cost the same per ton and also have somewhat limited functionality.
Gun barrel size tying in to tonnage is a completely unsurprising simplification to allow guns to inhabit a 1-dimensional spectrum. It might be reasonable in many cases...I can't really see lower-velocity 'sawed-off' cannon being attractive considering the issues, except maybe as a bombardment weapon due to bombs being strictly 'dropped' rather than thrown. And a higher velocity cannon variant might be technically infeasible.
