Ah... that vintage appeal...
The issue with the highs and the lows is something that plagues anyone without a mixed range of cabs - run her with a 12" cab should be spot on for your smaller gigs... I know your 200 has a similar tone and feel to my 100 so that ain't gonna be the issue... IIRC, you could lay that cab sideways and stick a 412 on top (where space is limited); it won't look out of place, and that should give you what you want...
If only I had the storage space...
Glad it worked out...
