Honestly, I don't think we can ever revive the site. Simply because of what the website is right? What i mean is that the forum model doesn't seem to catch on for social reasons anymore. We would definitely need a lot of the older members who liked this style because newer people aren't attracted to an empty site.
Sorry to be limply-negative but I think we all know it's the truth. I think the best course of action would be to open a site of wider audience. Like just make a gaming community website not necessarily centered around pokemon but games in general.
