Next to patreon viewing such things almost certainly as incest, I'd guess that's too much for DC anyway. He talked about a disabled character in the past (wheelchair, missing limbs or something similar) so we may see that, but I doubt he'll go further when it comes to disabilities.
I think DC mentioned that her arc will be somewhat similar to Roxxy's. So I guess we can expect her to actually start liking MC at some point. I doubt it's going to be as bad and he'll teach her how to be a little more relaxed. But we'll see, indeed.
I don't remember Lucy and Mrs. Smith but he made Annie's when he reworked her character:
The problem with making her story similar to Roxxy's that she have completely different attitude to MC. In Eve and Diane route she is kinda positive about him.
Sure, she's never been as super bitchy as Roxxy, but she certainly doesn't really care about MC and kinda looks down on him. Of course it won't be 100% like Roxxy - then her character would be redundant - but it sounded like we can expect Ronda to soften up a lot.
And for a bonus unlock the scenes with Mrs J.
