I didn't get the impression this film will incorporate much more than the theatrical cut did; light teasing. If it does go further though, just another reason to be so thankful the solo franchise became for all intents and purposes divorced from the Snyderverse outside of the first movie's brief voiceover about the source of the picture.
Honestly though it wouldn't half surprise me if the hints with Diana didn't replace anything at all. She likes him, he ends up liking Lois. More Batwank for your buck in that respect.
