Are there any other solutions, short of using BGP multihoming and having them try to get their own ASN and IPv4 /24 block?
For what it sounds like the customer wants to do, this really is the right solution. Most everything else has some level of 'ugly hack' attached to it, that can cause reliability/reachability problems at inopportune times (as opposed to problems that happen at opportune times).
If the customer is just looking for failover capabilities, they can take default via BGP from both providers, prefer one over the other, and use some other bits to prefer one provider over for inbound connectivity. They would not need very beefy routers for this.
That will get you basic service redundancy. Add a second router, and they can have some protection in the event of a router failure.
It all really boils down to what the customer wants and is willing to pay for. If they have services that need to be reliably reachable, then using a time-tested design is a prudent decision.
