No,
It would take a historic collapse of their voting base and meteoric resurgence of the UUP, the likes of which we haven't seen since the post GFA elections (when SF and the DUP rose to power). Since the UUP will barely run enough candidates to even theoretically nab enough of the DUP seats, we likely see some further erosion to other parties, Mainly Alliance but since they are busy shooting themselves in the foot dying on the strangest of hills, probably not. Even if we see a repeat of the losses of last election, that still leave SF + DUP as the largest parties of their respective sides, with Alliance being second largest but not counting as either therefore making zero difference.
The only way to break the deadlock atm would some GIGA chad 4d chess moves from Sin Fein after an utter collapse of the DUP to make sure Alliance is the largest party, then an assembly can be formed with any other largest denominational group, ie at that point SF.
