I've done some reading on cartridge emulators and their huge advantages over fixed damping rods. It seems that at my weight of 175, my money would be best spent on the Racetech emulators, some shims to get the sag right, and some fresh 10 or 15 wt oil. I will leave the springs stock for now. As I understand simply adding the emulators will reduce front end dive significantly as well as make the bike much more compliant over bumps in the road. The more I read about the emulators, the more they make sense. Damping rods are so old tech!
So what type of riding do you do? if its not to hammer down but just sport action I bet you might be happy doing what you describe here.
The oil wt will be the rebound control so it might take a couple of tries but beyond that - if you don't want the hassle of shopping for used forks and all that, it should work. Later you can always pop the caps and change springs if you like but I suspect this will get you 70% of what you want.
