I can see them possibly offering a few echo fighters post launch outside of the fighter pass as free DLC too (like ARMS and Mario Tennis got new characters). Would leave the door open for a few obvious ones: Jeanne around the release of Bayonetta 3, Dixie as a Diddy echo/Funky as a DK echo etc.
They said themselves that echos don't take much dev time, and dropping them periodically as limited time free DLC will bring people's attention back to Smash long after release
