A simple enough question to ask, but perhaps the solution might be complex to implement.
1. Why cannot the STARS continue pass LANAK, and feed directly onto final for 05 & 23, with defined speed control to provide the necessary separation?
2. This would reduce RT workload due to defined vertical and horizontal profiles. Clearly there will be occasions when ATC intervention will be necessary.
3. This style of approach would allow for a better CFP computation of fuel burns, thus refining [lowering] the ramp fuel figure on most days.
LVPs always a judgment call as to extra fuel to be carried.
4. The price of fuel has concentrated the minds of the bean counters even with hedging present.
Perhaps an ATCO or two [Miss D] from No.54 course might look at this issue [cryptic clue] and start the ball rolling !!
