As to the pot swap, even removing the bridge pick up will sometimes just exposed the block of wood running down the sound board so that might be a reach. Some of the 330's were completely hollow and I heard of a few odd duck 335's Gibson made that were not blocked. I get to them by taping the F holes off and using my fiddle tools to get at it all. I worked on a ES175 (1966) over the weekend, new nut and reset the intonation, cleaned up the saddles and dropped in two NOS V/T pots dated 1959 (where he found those, I have no idea!).
I don't know where you are located and if it isn't against DU rules to suggest it, I could handle the swaps for you once you find the right guitar.
Handcut and fitted bone nuts for example, I do for 30.00, more for Mother of Pearl or Ivory (yes, Ivory!).
Its not a business for me any more but I do all of the work for the guitars shops within 100 miles of me, custom stuff only. I also have wholesale accounts to purchase genuine Gibson parts (I am still authorized by Gibson, Martin for warranty work).
PM me if you are interested.

Since it is a player you want to hot rod, I would go the broken or second route, there is an ebay seller who sells only broken in transit and NOS stuff. The repairs are usually broken pegheads (why do they ship guitars with strings at pitch?) so you get them cheap. Neck repairs like that are relatively easy and surprisingly cheap to do.
The money you save going this route can be substantial, beat the guitar up some more and sell it as a "relic", lol.
