Hi Dick,
Well, You could always re-apply for the 'big chair' again, delete the controlled airspace, make it 'Simple' OCTA....or G or whatever.... create a 'new' FS environment, and then you would simply receive a directed traffic information service, one about the other and vice versa just to be 'sure', and arrange your own separation.....Zimples.....
I'm not too sure what the 'RPT' sector would think of that, but, Hey, GA would be 'well served'...(?)
Cheers...
