As mentioned, being a low pressure (relatively) cartridge, one could drill it out and do the insert.
The other option is to try to find an original barrel in a longer length. I know they made a 5" as I've had them before. If you can find one, having it put in is relatively easy.
The gun honestly isn't worth fully machining a new barrel from a blank.
I've re barrelled many prohibs for re registration as restricted. Mostly S&W, Luger and Colt. Some of which were manufactured from scratch, but we are talking more valuable guns where the machine time and material was worth it.
