Guess being the tallest of the group, 6'-8" rather makes it more uncomfortable.
Head is already touching the hardtop, but soft top is the frame, not the fabric.
Tried to modify the seat cushion to make more room, but not too well.
Seat back was changed to a thinner type, that helped a bit.
But no seat cover. Now seat is back to original and just drive for short times in the uncomfortable position.
But you can try to find a 190SL seat and retrofit that in as the cushion on the bottom and back are thinner.
Only hangup is the seat adjustment is not far back enough, due to the B post and the parcel tray being in the way.
Had my first Pagoda senior in High School and was 6'-6" fit was good. Best to have a white steering wheel, as the black one left rub marks on my pants all the time.
Switching to white, eliminated this problem.
See movie "Intersection" with Richard Gere, and in scenes show him sitting in the Pagoda, and he is 5'-11"
Hope this helps.
