That’s a nice approach. The fun exercise with Nashvilles is deciding just how much Tele and how much Strat you want it to be.I ran my Nashville with a standard Tele 3 way, with an "on/off" for the middle pickup. In my mind it was simpler since most of my other guitars are 2 pickups so the adjustment between instruments is easier (for me). My Strat used to have a 5 way, with an 'on/off" for the bridge pickup. No series or "out of phase" wiring since I found that I just don't use them.
I’ve often thought about putting together a Nashville Tele with a trem mounted below a cutoff Tele bridge plate, even though I don’t use trems - I just think they are part of what makes Strats feel and sound a certain way.
I could probably live with just a bridge, bridge+neck, mid+neck switching config on a 3-way if I really did away with the inessential. I rarely use the Tele neck by itself, nor the middle position on Strats.
