I'd roll with a G12 65 or the WGS version. That speaker loves any amp I've thrown at it..and it has more mids than the T75 by a longshot; unless we're talking about the early 1984-85 vented versions.
Funny you should mention both the G12 65's and old T75's;
I have both these speakers matched with Mesa V30's in two different 2x12 cabs;
Marshall 1966B (diagonal 2x12) 24" wide, '86 T75 + V30, and a Mesa 2x12 Vertical slant; top position: G12-65, bottom: Mesa V30.
Both cabs sound PHAT, without mud.
Also they can help with slightly balancing any stringent highs from amps.
3rd option would be the K100, but as you said yourself Beyond Black, while punchy and powerful, it does have a certain blandness to it.
Depending on which amp you want to use the most, you want to consider
-do I want my cab to almost add low-end to a thinner sounding (relative to...) amp?
-do I want crunchy mids, and/or add character, while still have a good low-end?
The K100's will add the least character, but will help the most in creating a big low-end foundation, that's not flubby.
G12-65's will add more character, still have a big low-end, but these typically want to see more signal, before their 'magic' appears.
For home/bedroom volumes, G12-65's may actually come across as too smooth.
I used to (and when it comes to the modern ones, still do) slag the T75's all the time, but after getting the Marshall 1966A with vented dustcap original T75's from '86, those became one of my favourite speakers. None of that shrill highs, scooped-mids BS.
