If you're still looking, Weaver Grand Slam or Burris Extreme 2-piece bases might not hang over the port... or extend forward past the front ring... But it looks like the bases in the third pic solve the problem (Leupolds?) as long as the spacing works with the scope.
(Yes, Warne Maxima front base either extends over the port or forward of the front ring. Not sure what their rear base does, for the .375-length ports.)
