He's saying it would not require a neck reset, therefore it would not mess with the original finish.
That’s what I did.If you hang around a bit....
You'll notice conversions come and go pretty often. They're always the "greatest thing ever" but I'd say they attract a hardcore GAS crowd like nothing else...chasing the 'burstness. I've seen a fair number come up online + local shops along with resto-modders putting one out there every so often. Folks freaking out over one this week will be selling it next week, play the long game.
Point is, you could find the right buyer for that guitar and fetch a conversion if you're semi-patient, let someone else have all the work done and parts sourcing for you while knowing you left a gem alone.
