Besides weight, is there any functional difference between road and mountain cranks with the same Q factor and crank leangth?
Sounds like a lot of extra work, and what will you do if you're not pleased with the appearance after grinding off the granny bosses? Just buy a 110BCD double, they're not hard to come by.
There is no guarantee at all that mounting the RSX's crank on the Exage's bottom bracket will result in the correct chainline, or satisfactory Q factor, either. BB's aren't expensive or hard to remove/install.
