if you like other site to connect, you need to build VPN IPSEC  between ASA to ASA to reach each other.

If you have lan segment  overlap IP : follow below document :

friend you can divide the subnet connect to INside of ASA to two part, 
and using PBR instead of using default route. 

that how you can use two route to two different next-hop in ASA 

note:- new ASA version support load balance.

Hello
can you elaborate on the existing setup - 
Do you have just the one external connection at present and wish to add an additional wan connection?

how you are you presently connecting to the other asa(s) what routing do you have in place
what other services are you running between the fws - (vpn/nat/encryption) 

Can you share at least the running configuration of your ASA?
