what is the best simplest (if any) to setup two wan ips (from same isp) on a metro ethernet network?

here is what i have:
2800 Cisco router
asa5506 firewall/router
metro Ethernet fiber transceiver
block of wan ips: & (available to use)
right now, this is the current setting:  (ISP) Metro Ethernet Fiber Transceiver <------> 2800 Cisco router<-----> 2layer switch with Sub-nets:

if we were to create a separate network, do we plug in a pnp switch infront of the 2800 which would feed both 2800 own wan ip and cisco asa5506 own wan ip? like this:  
(ISP) Metro Ethernet Fiber Transceiver <---pnp switch---> 2800 Cisco router<-----> 2layer switch with Sub-nets:
 "        "            "              "           "              <----pnp switch---> Asa5506 <------------------> 2layer switch with subnets:
or what do you suggest? see attached for graphical view of our intention.

thank you in advancemetro-ethernet-dual-wans
