Agreed; I have no idea how you'd implement that across multiple ASNs, which is definitely a requirement for multi-cloud or geo-redundant architectures.
Seems like you'd be trying to work against the basic design principles of Internet routing at that point.
You can configure your assigned network numbers that other AS are allowed to announce certain networks of your own. Not uncommon for in examples authoritative name server addresses.
