I think the problem here is that you need to ask an individual yes/no for each option as many might do more than one thing. hence they would not want to vote on a single solution? p.s. Not sure I would choose any of the above as the main first step, perhaps a conference meeting with all involved to discuss the issues and then a discussion with my head of dept who should be able to offer some sound advice on what we can hope to achieve with the resource we have and therefore match accordingly, varying that match as the situation changes..
