Right, onto some example figures then, a freshly built 2.0 fox on the red fluid (28.5wt) at about 120* oil temp, will, on a 30 stack on the compression, and a single bleed hole, will give roughly 150lb.force at 20inch/s of shaft velocity, and about 48lb.force at 4 inch/s.
The same shock, setup with a 60 stack on compression - gives about 76lb.force @ 4 inch/s, and about 190lb.force @ 20 inch/s
So as you can see, a pair of 30's won't give the same result as a single 60.
Anyhow, in case you find it useful, I sat down and went through some quick calcs, and if you ever wanted a single shock valved the same in compression as your twin #30 comp. stacks you'd want roughly an #85 stack with twin bleeds open (or 4 bleeds if you originally had two open)

I'll work you the rebound out when I have 10 minutes spare over the weekend if you like too.
