flow rate gradient along with composition gradient

I'm trying to run a gradient LC method by setting both flow rate and mobile phases in gradient mode such that the thod can cover a variety of compounds. Any suggestion about the method? Thanks!

One thing to think about with variable flow rate methods is that your calibration will vary with retention.
