Something which goes further than this, but works very well for my use case and would probably suit others in the WFH crowd: OpenMPTCProuter [1]
This handles failover between connections and also aggregates them using MultiPath TCP to maximize bandwidth & overall reliability at the expense of increased data usage and the cost of running a machine somewhere with a decent connection, even a cheap VPS.
I'm using it to aggregate ADSL, Starlink and 4G, resulting in a stable 250mbps/50mbps connection.
but then you face the same problem as when you have a VPN to a VPS, sites will see your IP address, see you are coming from a cloud service provider, and block you.
