Since several people have expressed skepticism about doing this I withdraw my support for this approach (substitute trustee). It would have questionable legitimacy, and I don't want that.
I will take a wiki vacation for about two weeks and then I will decide how and whether I will continue to participate in Wikimedia. I may make edits here and there but I won't be watching the mailing lists so if there's anything important please contact me at my other email address, moeller@scireview.de
Regards,
Erik
