My gut feeling is Riff Raff will actually be OK for you. I don't find them "thin", but they have a quite "hard" vibe to them that I don't always need.
Now I have the Stormies in a 61 reissue, that has definitely warmed that guitar up (in comparison to 57 Classics, which I believe are already warmer than the 498/490). But I've also been revisiting my Faded SG with the Riff Raffs....
Basically, I'm finding I'm LOVING the Faded with RRs now that I have another SG that I find more versatile. The new 61 has the really skinny fast 60s neck, it's got the Stormies that can do both mean and mellow. It's more the sort of guitar I'd strap on for any style.
My Faded has a big fat neck on it, and with the Riff Raffs, it just punches holes in things! If I want a guitar for "rock" - for me, this is the one to reach for now.
Don't rule out Riff Raffs - and Black Dogs is something I'd like to hear too (from Tom's experiences).
Finally, didn't BKP used to do an AV Mule as an option? But I remember reading somewhere on here that it's pretty much a Riff Raff then? Very SLIGHTLY different wind, but basically a Riff Raff.
EDIT - I'm starting to regard this "hard" vibe I keep talking about as probably the AV magnets talking (I get the same out of AV in strat pickups, etc). Maybe, if AV is what you want, then Riff Raff is where you ought to be going?
