That should be a great sounding combination, and yes, it should sound great even at quieter levels, so go right ahead!
As long as we're at it, I thought I'd share a couple of other cab combos that have really been eye openers for me with the LMII (in a good way). It is no secret that the LMII seems to work very well with Epifani and Bergantino cabs, with varying success from model to model. But two other combos I have tried recently that really seemed to click are two EBS neo 1x12's and a single 4 ohm Sadowsky SA410.
Yes, I know the SA410 is made by Bergantino, but its voicing is quite different (more midrange push/warmth, not quite as much low end extension). I have found the lows to be ever so slightly reticent with some SS heads (the SA410 being designed for tube power, and responding gloriously to tube heads/amps), but with the LMII set 'flat', it was butt-kicking booty, with slamming articulation like you wouldn't believe! That amp really brought that cab alive!
I have had a single EBS Neo 1x12 for a little bit, and while I love its midrange presence/articulation/clarity, and its high end is perhaps the best I have heard in a 1x12, the lowest notes, while well defined, were not as full as I generally prefer. Adding a second cab really helped out in this department, but I feel like the LMII just has a knack for bringing out more good, stout, low end response from a cab, and it just made those two EBS 1x12's stand up and fight! That is a very loud, very full, very clear, very punchy stack. I need to update my 1x12 shootout, but with the right amplification, I see great potential in those neo EBS cabs.
