To have a successful journal, you don't need a particular university's researchers to publish in it, even if it's a very reputable university. You need everybody working in the field wanting to publish there. All the supposedly really simple solutions suggested in this thread don't work. It's not like academics haven't thought about it.
Sure, that's why you get a particular university's researchers to publish in it. That's exactly how you start making it so that everyone in the field wants to publish there.
They may have thought about it but has anyone actually tried it? I'm genuinely asking.
Edit: It seems they have and it worked. See mjn's answer below.
