It sounds to me like you're looking for classic link load balancing. So.. do you want outbound link load balancing or inbound? Here's how it works with LTM / DNS:

Inbound: set up a WIP in DNS for each service. Each SP has a VIP. (btw, you can accomplish this with F5 XC Cloud managed DNS and LTM. don't even need DNS license for that.

Outbound: Set up aa all-ports forwarding VS on the inside leg of your LB. The pool for that VS has each router's GW as members. Set up persistence as you like it.. source / dest.
