I can't say for sure, but I suspect if you removed the extra CVO/CVI and created a custom VIP component for your custom IP that you could get rid of the extra frame buffer. If you dropped the extra CVO/CVI you remove the need for the 25.175Mhz clock so you shouldn't have to worry about the two clocks being locked anymore.

If you already have your custom IP developed and the memory bandwidth and FPGA resources to spare, it may not be worth the work to convert it to a VIP component.
