It can not. File size is not known until after the file starts arriving.
Sometimes not even until it has finished arriving.

The best you may possibly do is create a custom external ACL helper to
scan store.log for previous file sizes of requested URL. Then use
tcp_outgoing_address based on a best-guess.

This however breaks completely on:
* new and unknown URL,
* changed URLs,
* dynamic URL (very common!),
* and most websites updated by their webmaster between your visits
    (almost as common as dynamic URLs).
