Look at the provider mechanism used by the mod_proxy and
mod_proxy_balancer to select a load balancing algorithm.

(grep provider modules/proxy/*.[ch]

Then it's just a matter of changing ProxyRemote to implement the
default provider, adding a little string config option to choose a
non-default provider if you want it, and implementing the the new
provider.  It would have a fair chance of being integrated into
upstream Apache to allow other modules to extend the selection
