It seems like it may be nip and tuck with a spindle that short, but as John E says, if it will fit it will fit. Your best bet might actually be to try a double crankset with 110 BCD or smaller so that you can put on a smaller inside chainring which might give you the clearance you need if a 39T won't do it. This could be a positive for touring. With 110 BCD you can go as small as 34 teeth, giving you smaller gears than normally available with a double. I have a 48/34 on one of my bikes. It works great. On my normal flat riding I am always on the big ring, but I have that tiny one to handle even pretty serious hills if I put on a 28T or even 34T cog in back. A 94 BCD would allow you to go even smaller, but I don't know if doubles come that small.
I am not too up on the model numbers, but is that a cartridge bb? If you used cup and cone you could just purchase a longer spindle from someplace like HarrisCyclery.com which could be swapped in a matter of minutes without completely replacing the bb. But then swapping a cartridge bb is probably just as easy.
Still another, even simpler, compromise depending on the terrain you might be touring one would be to put on one smaller ring up front. With a relativlely inexpensive XT rear der you could spin on a megarange 11-34 7sp freewheel. With a single 42T chainring this would give you 7 gears from a pretty low 33 inches to a pretty darned big 103 inches. There are also 13-34 and 14-34 which offer more cruising options but lower high gears.
There are many ways to approach a solution. These are just a few alternatives.
If it ain't broke, mess with it anyway!
