As next try I would add some haproxy-lb and change the transport_url to the VIP, this should afaik reduce the amount of connections to 1/3, but I dont know if there are any drawbacks jet.
To my experience, you really don't need to do this, oslo.messaging takes care of reconnecting to another node if one fails. Though you may want to randomize the order in transport_url. If you use puppet, you can use the fqdn_rotate() function to achieve it. i think that that behavior is consider deprecated. at least i recall converstaion in nova irc channel before about not advising operators to rely on that for loadblancing and instead suggesting they take the ha proxy approch.
