No. IdPs don't know about attributes, data sources do. You can connect either IdP to the same data sources. Even if some dumb organizational limitation prevents that, you can also use SAML attribute queries to make supplemental requests for attributes from those systems using a Shibboleth SP as long as the systems share a common identifier of some sort.

Gateays are not a Shibboleth use case.
