I am only considering one router (consumer level stuff). Here is my example:
I am afraid you are tailor making your case. We could just as well have an even more clueless customer that simply buys a 4G/5G router and attaches it to the inside of his LAN in addition to the wifi router he got from his DSL/cable/xPON service. Guess what will happen? It wont work as far as IPv4 goes but it _will_ work with IPv6. As for the tailor made case where the customer buys a device actually made for this, said device would also implement IPv6 for dual WAN. Plenty of options for how the device could do that, including the possibility of doing 1:1 stateless IPv6 NAT or simply presenting both prefixes to the LAN and source route to the correct ISP.
