Multi vote Kaizen board

We have recently created a Kaizen board. This contains technical debt stories, retrospective actions, non critical bugs, nice to haves, time savers, utilities etc

We have a dedicated support engineer who is allocated to supporting our live product. During this time he can pull an item from the Kaizen board if the support queue is quiet. The question is which one should he pull?

Using multivoting the team can vote on which item is the next highest priority to be pulled once a slot becomes available.
That item enters our Kanban board on it’s own work stream, moves through the pipeline and is subject to the same WIP limits as other items.
