I would consider using basic.get with noAck=false for this. The basic.get method offers a pull-API, where the client asks the broker for a message and the broker replies with either a message (in a basic.get-ok) or a basic.empty indicating the queue contains no messages.

This seems like a lot of work to replicate what basic.get offers ootb. Is there a compelling reason not to use basic.get for your purposes?
