I'd really like to see more Guybrush/Elaine interaction as well, she doesn't necessarily have to be around all the time, but an episode like Lair of the Leviathan where Elaine is the eyerolling woman that Guybrush has to work with instead of Morgan would be awesome. I really liked all of Guybrush and Elaine's interaction in Tales, so I'd love to see more of it.
I'm not so sure about the kid angle, but given that I felt that way about Guybrush and Elaine getting married in the first place and that (IMO) worked out fine I'd certainly give it a chance.
