Creating Small File Sized Proxies with Mixed Frame Rates

Hi,
I have been searching far and wide and I cannot find any good info on creating proxies for mixed frame rates. I would like to know if theres a better and more efficient method that I am currently using. 

I shoot weddings using a variety of frame rates and resolutions and I would like to know what would be the best way for me to create small sized proxies that I can send to a remote editor online.

Currently I am interpreting all of the footage to 23.976 in Premiere Pro and then right clicking all of the files and selecting create proxies in which it creates proxies in Media Encoder.
