Well, my vote is for "keep the Clipper as it is".
I have two alts who both have only a Clipper and a Courier each. The Clipper is excellent if you want only 1 or 2 ships: cheap, fast, agile, roomy, decent armament. Yes there are ships better than the Clipper in each of those categories, but no ship combines them like the Clipper can.
And it seems reasonable that for each pad size there ought to be some ships at the bottom end of the size range and some at the top. The Clipper, Orca, and T7 are at the bottom end of Large (and priced accordingly), just as the T6 and Keelback are at the bottom end of Medium.
