Much as I would hate to see the demise of the 'Reds' in their present form, two options spring to mind:
1. More sponsorship from British industry.
2. Take a leaf out of the RAAF book and have the 'Reds' as a secondary role for Vachchlley Instructors.
Option 1 would preserve the important overseas displays.
Option 2 has been done before, vide 'Yellowjacks.'
