I don't think it will happen. The merger only occurred just a week or two ago. Filming for Endgame ended around a year or more ago, considering they filmed it right after they finished filming Infinity War, leaving too many potential legal issues and too much trust on the merger being successful. Kevin Fiege also said Endgame won't end Phase 3, and Spider-Man: FFH will, so we're more likely to see a post-credit scene involving the F4 or X-Men in that film.
