tower,
leaving you high because 34R traffic want to stay high due track miles,
I'm not familiar with your SOPS but it shouldn't trouble a jet operator to be asked to "expedite descent to xxxx". My jet won't burn any appreciable amount of fuel flying level at 3000 feet vs 6000 feet, nor will it burn any appreciable amount of fuel descending at 500 fpm vs descending at idle thrust then flying level at 3000 feet.
The pilots might prefer one or the other due convective layers and turbulence, but that doesn't preclude you asking.
But as I said, your SOPS are your SOPS. I'm not suggesting you vary them, but maybe there is latitude for frequent operators to your airfield to engage in discussion behind the scenes about what might help with minimising delays.
