yes and no! yes you could, if you get a barrel that's short chambered. you would then need a finishing reamer in the caliber you want to go with and a set of headspace gauges and the measuring equipment required to measure the chamber depth.
no, if you don't have this equipment or the skill set required to do it properly and safely. setting the headspace properly is a very critical step in makeing the rifle safe to use.
besides the cost of the barrel, you are looking at between $300-400 for the tools and equipment required to chamber the barrel.
