U have to connect a switch even if the connection doesnt break between the routers. Bcoz, for HSRP to work, both the routers ethernet interfaces and their VIP sholud be in the same subnet. If u directly connect them in a firewall, its not possible as each interface in a firewall will be of a different network. So the design would be like this:
