Which can't be done because it invalids the point of using CloudFlare!
CloudFlare is used to protect your site from DDoS attacks and ransoms. It has to hide the IPs of the servers otherwise attackers will DDoS the servers directly, bypassing CloudFlare.

Also, if you serve a very large amount (as in different, say tens of thousands of different images) of data, 1 % of traffic is not enough to keep the other CDN caches warm. I know of at least one site that works this way which has allowed them to weather CDN outages.
