Could you share any details of your plans?
I have previously used a 1200mAh 2S LiPO battery (an airsoft battery) with the LT1963. Very quiet, of course. The dynamics are slightly restricted, and I think this is due to the 70 or so ESR of LiPO.
This SMPS DC filter has been popular at diyA. I have the parts, I guess I should try it out. Thread here. I input DC for the stack to the Allo Kali, which does have two input inductors and probably similar circuitry.
