Are you sure that's what you're after?
The reason I ask is that most selmer macs come in two standard (and very similar) scale lengths - longer scale tends to equal better tone and, in a purely acoustic setting, tone is king. There are 3/4 length student/child models, but they're tuned much higher than the normal EADGBE as a rule. In an electric setting you can get away with it, but acoustic playing is pretty unforgiving and you'd get string buzz, a general lack of 'fizz' off the guitar and all sorts.
BUT there are ways to make life easier:
- choose a guitar with a slim neck (others will know which makes, I don't have, and haven't had, enough guitars to compare fully)
- get the lowest possible bridge to lower the action (within reason - again, tonal considerations mean that GJ guitars are set up with a higher bridge). Just to take examples I'm familiar with, Manouche guitars (now JWC guitars) offered 19, 21 and 23mm bridges. I understand that other makers go much lower.
- a GJ guitar might ship with an 11-gauge string set; swap it out for a 10.
