If you want to stay in the higher output range, Ragnaroks would give you a leaner low end/low mid, but it's definitely going to give make for a midrangey combination - I like that but YMMV. I'd stay well away from Warpigs if you find the Juggernauts to be muddy and lacking brightness.
Personally, I'd strongly urge you to look at lower output options such as the Black Dog, which has a naturally tight and clear sound with plenty of midrange grind, plus the more open character from not being too heavy a wind. I think it'd be a fantastic choice for your application, especially given your thoughts on the Juggernauts.
You could even consider a Riff Raff, which is brighter and more open again. Don't worry, neither the Black Dog nor Riff Raff will sound weak or "vintage" in your guitar.
