I don't see a way to modify this circuit easily to change the rates, you have two variables to change to keep the duty-cycle 50/50.

How about a dual-gang 100k pot? You could add a series resistor of around 47K to adjust from 50K to 150K? I looked for a smaller trimmer, but dual trimmers apparently don't exist.
