Been there, done that.... I've already stated my view on the
scalability of such arrangements.

It also complicates every peering relationship and multi-homed
customer connection, as you have to worry about both multiple
external AS's and your internal routing redistribution from all
of these regional routing clouds.
If you presume a fairly dense set of interconnects among transit
providers, then you're not going to get a significant improvement
in latency despite the added complexity.
