Given that Elly was all about how something that was definitely someone's fault occurred because it was fated to and how John decided to buy peace by not letting the issue come up, the necessary confrontation with her own ineptitude, inattention, entitlement and thoughtlessness never occurred within the strip itself. Elly's refusal to learn her lesson from that led her to such triumphs as getting her ass in an uproar because April didn't want to make nice with a violent thug, not believing her when a thief threatened her and letting her asshole husband and cowardly idiot son steamroll the kid into accepting the Housening lest she become Deanna's maid.
This, of course, means that the biggest problem that would face a new team would be how to make Elly see the error of her ways without it looking completely unbelievable. It seems to me that the volunteer work Elly would be shown to be doing would be the best jumping-off point for her letting the skeleton out of her closet and putting it at the head of the table; what that means is that she'd have the sort of bad feeling everyone in the Star Wars universe has at one point or another when a certain child is concerned. It would seem to her that said boy or girl's parents weren't as attentive as they should be and, well, her own past as a negligent idiot awash in self-loathing and under-acknowledged doubt would galvanize her into action.
Said action, of course, would be telling the younger woman not to follow her own stupid example; it's not in Lynn to write Elly as the cautionary example she looks like to yours truly but a new staff would probably do so.
