Route servers do not add their AS to the AS-path.
Wouldn't it be easier to just ignore them?
Treat them as the cable between the BGP speakers.
It's the RS clients that have relationships with each other.
Nobody has a relationship with a cable.

This allows providers, customers and customer's customers
to all exist on the same route server and have proper relationships with each other.

Suppose AS-1 is Tier 1; AS-2 is Tier-2 and AS-3 is a customer of both AS-1 and AS-2.
AS-2 is also a customer of AS-1.
They can all connect to the same route server.

Regards,
Jakob.
