I could get a 6 speed Regina TT block on but as you say, the gears are too big for normal/club run use. Especially as I have 53/39 on the front. (Not at home and I can't recall the rear blocks range offhand).
The 5 speed Suntour block fits well (similar clearances to your block) and actually runs near faultlessly with the 8 speed DA Shifters.
I might have a play with some other blocks and remove a few rings as I did 82 miles on mine at the weekend on a fast clubrun and although it was fun giving done of the carbon boys something to think about, it was bloody tiring!!
Aaah, cunning.
