If it was £100 just to cut the corner of Doncaster's zone, absolutely not
If it was £5 to get a priority transit through Manchester's airspace rather than squeeze through the LLC, I suppose I would.
If the persons responsible for the financial side of operating CAS are looking at other ways of funding it, they need to plan on regular use/income, which in the UK is going to be commercial traffic not weather dependant grass roots light GA doing VFR. The heavier end of GA is likely to want to be up high for fuel efficiency and increased TAS, and the crew will be IR rated and presumably wanting to be in CAS most of the time either due to airspace complexity or to keep away from light GA bimblers.
It would not be worth the admin costs for £5, also many GA pilots seem to bleat about a £5 differential in landing fee between Airfield A and Airfield B when choosing a destination, so where those bleating pilots currently can request a CAS transit, any fee will put them off a CAS transit and push them into the choke points between CAS boundaries at the lower cruising altitudes.
