I understand the budget constraint. My 445 build was delayed several months because of that.
I assume by blue flashlight you mean the hotlights host. Two CR123As don't come close to fitting unless mod the host. The second one sticks out the back by about half an inch which is why I used 3x10440s in my PHR build. Your best bet would be to cut down the plastic spacer like DTR showed for the 18500 mod. if you do that leaving out the spring he attached and shorten the tail cap spring so it only sticks out enough to make contact you might be able to fit two 18500s in it. I'm not sure if protected ones would fit or not since the 18500 is about a mm or so longer than the 123 and the protection circuit usually adds about 2mm to the length. FWIW my protected AW brand 123s are the same size as a normal non-rechargeable lithium but I guess to keep it the same size they had to make the cell a bit smaller losing some capacity in the process. Just remember to measure thrice and cut once using a sharp saw blade since the plastic spacer/pill is really soft and breaks easily.
