Has anyone tried their Mark Vs with 6V6s? Does it require any specific type of 6V6s, or would any work just fine???

Even if you had adjustable bias so you could properly bias the 6V6 tubes, the plate voltage is still going to be on the high side and probably over 450V. The JJ 6V6 may take that, but many others will not.

If you search the most recent version you will find that "6V6" only appears twice in the manual, both appearances being in the feature article On Triodes, Pentodes and Irishmen that appears in every Mesa manual. Thus, I would assume they have concludes that the 6V6 is not an appropriate choice for the Mark V.
For what it's worth, I am pretty sure that I remember reading something about 6V6's when the Mark V first came out. I am pretty sure it was Variac power and 45 watts, but don't take this as gospel. I would always trust the most recent manual more than anything you read on here.
Don't forget, you can always call them if you really need to.

Well, according to Mesa, apparently 6V6s work fine if I use the variac power setting. I'm just not sure what would be the required bias range for the 6V6s to work with the Mark V...

But why? Why do it?
I like 6V6's but they're of limited use. 3 modes on the clean channel and maybe Edge mode on channel 2.
The high gain settings are already lousy with bass and flub. You're only gonna exacerbate that with 6V6's. Just listen to a Fender Champ on full tilt then times that by 10.
