Bertie, I am not sure you can get an exemption from the law. The law is that under UK regulations single pilot PT stops at 60.
Even to change Poloce Aviation to Aerial Work would require a change in the law. That involves work for someone in authority who would probably rather not do it.
However, should there be a decision some time that TFO's should be re-classified as Technical Crew Members then maybe that would help the cause, on the other hand, our secondary role of casevac may be the sort of thing that means we have to stay as PT.
I suspect that reclassification from PT to something else is our best hope, but I'm not sure it will ever happen, should the opportunity to make the case for it arrive, I will be jumping on that bandwagon and talking long and loud.....
