Weapons Mods that Change Caliber

[oxymormon]

I've been looking at making weapon mods for an 1851 Colt Navy Revolver that will allow the player to use an upgraded conversion cylinder. As in, the only cartridge conversion currently available for that weapon is .38 Long Colt, which is obsolete and only roughly half as powerful as a .357 Magnum. I've been racking my brain to figure out a way to have an upgraded, player-crafted, conversion cylinder mod that will allow the caliber of the weapon to be changed to .357 Magnum. I'm semi-decent to mediocre at scripting, so trying to figure that out on my own would take until Fallout 4 is released. Any pointers?

hmm not with the weapon modding system, the vanilla game delivers.

 

But making a crafing recipe that uses the original weapon and the "conversion kit" as input and the new weapon as output would work.

The bad side-eddect is that you would loose the weapon mods on the base weapon, though, because you essentially make a new weapon.
