Maria’s comment about BGP multihoming is correct and reasonable if you have one location/few locations and use access circuits that providers are willing to run BGP over. It doesn’t help if you are trying to arrange low-cost resilient internet access over low cost FTTx/cellular to, say, hundreds or thousands of branch offices. It’s one use-case for v4 NAT which, even this NAT denier, agrees works well.
The goal is to make it low-cost. Otherwise BGP could help, but load balancing incoming traffic does not sound trivial. Another perspective: Instead of two cheap uplinks with speed x, I expect two uplinks with speed x*2 to be cheaper than two uplinks with speed x and BGP.
Is your solution based on any published standard, Jonas, or has it been implemented as a feature on any commercial small router?
No, this is no standard. I submitted a patch to OpenWrt (Router Linux Distribution that can run at x86 hardware and consumer routers) to implement this - the patch that I am using right now. One developer complained about the fact that this is not based on any standard. Another one suggested discussing this concept here.
