That's a good question. There seems to be a distinct lack of desire on the part of the relevent authorities to release frequencies for what they call 'recreational use'. This being a lose phrase for any frequency not allocated for a form of air to ground communication. I'd say there are definate merits in having them and the low level route could be one. The unfortunate bit with this is that it would only work if everyone used it. When you start to get into any form of compulsion the feathers really start to fly! There is no 'zone' frequency for the LLR because the Approach radar facility at Manchester is provided by NATS on contract from Manchester International Airport Plc. If you were MIA Plc would you want to pay for the controller hours neccessary to provide the service to GA in the LLR which provided you with no income? I'm afraid this is a fact of life in this modern world.
