Pete,
If your going to go that route, make sure as Carl mentioned that the fluid your going to use is compatible with the oring material that is in the components. Buna, nitrile, viton all have different characteristics and some fluid will attack and degrade them.
Best bet, and easiest to do, is a fluid change every year. I do it on all my bikes, and can have all the systems flushed with new fluid in 30 minutes or less. I know your wanting less maintenance, but motorcycles just dont work the same way as an automobile, and contrary to popular belief, auto's have a scheduled maintenance on the brake system fluids....
