While I do have a lot of ideas for my own little fan things for the Mother series, I'd feel really weird putting them up on a wiki... '-'
I have a
massive to-do list for WikiBound that I am drowning in, too. ;-; (I've been conveniently putting it off by making plushies instead.)
Otherwise, I'd help out! Keep in mind that if you're starting a wiki, it'll suck up a lot of your time taking care of it. Just know that there's a large responsibility behind growing a wiki.
