I certainly don't know the AA market as well as many others around here, but to my knowledge there are no other lights that use the same UI as SureFire's A2/L1/etc. (I assume that's what you're referring to, and not the interface on models like the E2DL?)
As far as I can see, you've got three options:
1. Suck it up and use a stock SF (L1, LX2, L2, whichever) and deal with CR123 cells (recommended if your priority is the UI)
2. Suck it up and use another brand's AA flashlight and deal with not having the 2-stage twisty UI (recommneded if your priority is battery format)
3. Invest time, effort, and possibly excessive money into some kind of legoed/custom/something light that has all your desired features (only recommended if you're looking to expand your flashaholic horizons)
If it were me, and I wanted what you want, I'd get a SF 9P (it is of proper length to accept 2xAA), fit it with a tube/sheath so that the narrow AA's don't rattle around in the body, put a Malkoff M30 in it, and find a modified, or the parts to modify the tailcap with a resistor for two stages.
I've thought about tracking down such a tailcap for my C2/M60, but it hasn't been worth the effort and money when I can just use my L1 instead.
