Russ, just today, I saw an announcement for a whole new series of Guild acoustics...
new Guilds. I think that former Gibson icon-acoustic-wizard-designer, Ren Ferguson (who left Gibson) has been working with Guild/Fender.
As for the Guild from you, no, the neck is fine and dandy and I am happy about that because it's not a simple fix on a Guild, it's anything but routine. But, can be done well in experienced hands.
I am going to put a new pickup system in it and there are some new ones these days that are definite improvements to get rid of the piezo quack.
