UX Discovery workshop – Large teams

I need to run a discovery workshop with a large team - devs, managers, leads (around 15) to get alignment on the feature set and MVP (basically going through the current state and figuring out what's applicable or not) A lot of research has been and I have a high-level view of the pain points and needs of the users.

I am thinking of making a list of features cards for the meeting and asking the participants to vote if it is still relevant? Any ideas on how to approach this kind of workshop?
