Participant polls have no history of being accepted for action on large item proposals. They are not as secure as mag+stake.
Large action polls (development, funds, and whitelist), while having no official structure, parameters, or processes, generally require a large % of participation (15% 20% 25%? It is difficult to say due to the scattered information out there).
I doubt a participation poll will be supported by those with control over the whitelist. You may wish to confirm this before making the poll.
We are currently having some amazing discussions regarding what makes a poll "actionable". This proposal will undoubtedly be part of that conversation.
It would not be. Only mag+balance polls are actionable at this time.
