That's a good plan - I have my Jaguar where I want it, other than *possibly* some less worn Klusons and as mentioned getting better chrome plates. I could replace the pots with full-sized CTS, but don't want to fix what isn't broken either. Wiring is cloth, pickups are SJAG-1s, vintage bridge/AVRI vibrato and I'm very happy with it. Even got a jumbo re-fret (prob. not to everyone's taste on this guitar though.) It sounds the way I always wanted a Jaguar to sound.
That said - there are few times I play it and don't sort of wish I'd got an AVRI instead - just because I like Jaguars so much. AVRIs are much more comfortable to hold (contours,) body is radiused nicer and the nitro feels better/less rigid and cold. One of the things I think is less than stellar on mine and other MIJs, is the inlay work (the black side dots are a bit sunk from the factory) and the fretboard wood, which is very open grained and almost rough. I also prefer the AVRI (or even Squier VM) side dot pattern to the seventies style black dots/beneath the fretboard. The matching headstock is a big reason I was ok with MIJ however - wasn't available on AVRIs at the time (~2002 ?) and plus, I've never seen an MIJ neck with as much flame as mine - sounds/plays good so won't be swapping it
