It allows us to use less air per stroke (out-in), and since the solenoid still sees 60 psi we don't have the pilot pressure limit on the downstream side of the regulator.

In order to regulate the retracting you would need to use a separate solenoid that is regulated down prior to it going to the solenoid.
You could do it your way, but you are still using 60 PSI all the way up to the point your 2nd regulator is (which is pass the solenoid so you would still lose some extra pressure).
But it would 'work'
