I have a 26-42-guard New Albion setup, and although the 16 tooth shift is 
huge, it's pretty manageable if I'm not in a hurry. Maybe you just need a 
new "middle" ring and chainguard? It's also possible your chainguard is big 
enough for a 42. Going from 38 to 42 is about the same as changing 1t in 
the back for the higher gears (i.e.: a 42x11 would be like getting a 10t 
high gear with your 38), so is pretty noticeable. That would give you a 1x 
plus bailout, and you'll probably use the 42 for about 90% of your riding. 
How often do you use the 26x34? If rarely or never, I'm sure there are 
11-32 or 11-28 cassettes that will work.
