I think you can solve this by using weights in the parent relations in PS1 and
PS2 to respectively ES1 and ES2. In PS1 you should have ES1 as a parent with
the highest weight factor (ackting as the default) and have ES1 as a parent
with a lower weight factor (ackting as fall-back)..

I'm using at the moment a quite similar strukture with a toplevel cache and
a fall-back (secondairy) cache..

Cheers, Henny
