-Once I choose my gear combo I plan on using spacers to align the chain on the existing hub and bottom bracket. Will this work?
1. You will need a tool for this. The type of tool depends on what you're working with. (Pictures please!)
2. I did that on a cheap steel crank. I drilled out the rivets, and replaced them with nuts, bolts, and washers to center my chainring. It worked.
3. There are two ways to get a straight chainline: move the chainring, or move the hub on its axle. Moving the chainring is easy (just add more or less washers after completing #2 ^^). If you move the hub by rearranging spacers you will probably find that your rim is not centered in the frame anymore. You will then need to have your wheel re-dished. My LBS charged me $10 to do this.
