Well, I don't have any experience, but I'm going to try using Battery station R123's and a downconverter just like you.
Also JSBurlys has R123's
Waion (I think,maybe it's AW) has some as well he sells with the nano charger. These are UNPROTECTED lithium-ion so they can be damaged by over discharging.

How about two Pilas 150s's? they are about the same dimension as 3 123's and have very flat discharge curve. Or even better, two 150a's which are fatter but the same lengths as 3 123's.

I'm using (2) Pila 150A's in my 2C nFlex modded Mag. It works great.
