Yeah, if you go with the spacers, I'd recommend you just put them all on the NDS, then re-dish yourself. Not only will you avoid the lower limit screw range problem, but you'll be strengthening your wheel. It's really not tough to re-dish. Just take 1/4 tightening turn all the way around on the NDS spokes (that's counter clockwise when looking at the bottom of the wheel from above. Keep tightening 1/4 turn until your thumb jambs between the rim and chain stay the same on both sides.
