doubtful, I'd think more along the lines of Quinn + Valor.
meddler actually recently commented on a "double" champion release of having two individual champions released at the same time:
"I don't think we'd want to do two new champ at once, we do like the way people have time to experiment with a champ, learn how to play against it etc, plus the way each champ gets to be at least a brief focus point on release. I'd imagine we'll see some cases of closer releases at times again though, like the shorter gaps between Gnar/Azir and Kalista/Rek'Sai last year.
