since no one else replied I will. I use MATY's object remover. It works great. I don't understand why you object to using it - I have not been able to find anything else that works. Since you can't use moveobjects cheat, I don't know what else to tell you.
I don't know that can be done but you can have the illusion of an elder having a baby by using the mod here: http://www.insimenator.org/index.php/topic,69861.0.html -- I use it all the time & it works fine except no baby belly because the elder body does not have that state.
