two RCR123 cells will have a nominal voltage of 7.4v, far more than the 3.9-volt-max dropin can take.
Secondly, this light only accepts AA-size cells, 123-size cells are far to wide to fit.
you could use two 14500 li-ions but you'd have to ensure that your dropin was rated for that much voltage. a 9v-max dropin would work, but frankly, you'd be better off with a normal L2 and a 18650 cell.
@JohnJ512 no, for two reasons:

Hi Can this Max 3.9v & 1000mAh 338 Lumen XR-E Led use 2 RCR123 3.7V Li-ion with 800mAh Battery to drive it?
Is that will boost to 350 Lumen? 2 RCR123 3.7V Li-ion with 800mAh will have Total Power is 5.92Watt/ XR-E Led. Can that be done to Max it.
