That seems rather cumbersome. pg_basebackup is a run once, and then it 
dies. The slot would have to be created before running pg_basebackup, 
and destroyed manually.

It would make sense to provide a new option that would tell the server 
to recycle segments until they've been sent to this client, or until the 
client disconnects. But that would look quite different from 
pg_receivexlog's --slot option.
