I do. Not sure I would necessarily say to "tighten" things up so much as push the front of the preamp to distort it slightly; the Mark 5 is plenty tight and percussive all on its own.
I use it more as a clean boost, with the Drive knob almost all the way down and the level way up, and I like the added depth I get just by giving that little goose to V1.
Pretty sure the TS and similar use opamp/chip clipping not diodes, but again, not that it makes much difference. And I don't have any problems with diode clipping per se, just pointing out that Mesa doesn't use it for clarity.
I played Dual and Triple Rectifiers, Mark V/35, Recto-Verb, Fillmore, and the Badlander.
All were of great construction. The Badlander produced the most gain of all of them, but it still needed a TS-9 to develop a tighter gain structure.
But honestly, I do not fault Mesa because I don't think they were shooting for this type of sonic character.
Even then, the Badlander with a TS-9 didnt have the gain production, percussion or midrange "snarl" that @Don O's 1997 #8280 Valvestate Bi-Chorus 2x12 Combo has.
Even with the gain on '10' its fully useable, never muddy and cuts like a knife.
The 8200/8280 are the best sounding amps I've EVER played, second place is Engl Fireball/Inferno.
Chuck Shculdiner of Death used stock Valvestate 8100's on his recordings.
Now I full understand why.
