I think you bit underestimate content of EX. Personally I believe that each child would be able to fill page about at least similar extent like current Elmenhilde's page and some even more than just that, when will be described properly. I can do that if you want. Although it might be better to wait on JeruTz's complete translation to have better source for inspiration.

P.S.: Also I have big feeling that this is not the last time that we heard about Issei's children. ;)
