I always wanted Erica and Adam to somehow have a kid together

Is this actually an impossibility? Erica always turns out to have one mystery child or another, would it be so outlandish? Wasn't there a storyline in the early 90s where Erica was with Dimitri and Adam was in some custody battle with Dixie over Jr? Couldn't AMC rewrite history and say that Erica had a one night stand with Adam and then "took off" to Europe for a while with Dimitri when she was really popping out some kid in a convent in Idaho? Or something? I don't know! lol
