Quick question though, would I be able to hot swap between a longer barrel and a shorter one or would I need to monkey with the lower receiver?

First off you need to realize that a short barreled rifle (A rifle with a bbl of under 16" in length from the bolt face to muzzle) will need to be an NFA registered rifle specifically called an SBR, or short barreled rifle.
To achieve a 14.5" barrel without needing the NFA registration, you'll simply need a 1.6" muzzle break permanently affixed to the muzzle of your rifle. That means blind pinned and welded.
If you have a registered SBR, as long as you marked it on the form, the various barrel lengths you would be using, then you can use any of those barrel lengths by swapping uppers. It's recommended to get a grip with a storage area (such as the TD, or the Magpul MOE/MIAD) to store the NFA paperwork in, in case you're ever asked questions about it by an LEO.
Also there's no such thing as hot swapping a barrel unless you have a thing called an LMT MRP
You can howevor have multiple upper halves, that can be put onto a dedicated lower by simply removing two takedown pins on the lower receiver, removing the upper, putting a new upper on, and pushing the pins back in place.
It's VERY simple to do that.
