Appending the "/.well-known/openid-configuration" to an issuer identifier that has a path component per §3.1 of Discovery  seems like it might contradict RFC 5785 (or at least not really be in the spirit of RFC 5785). The first paragraph of §3 of the RFC  talks about the path component beginning with the "/.well-known/ and question
#4 in the FAQ  talks about why per-directory well-known locations are not defined.
Is this okay? It seems kind of iffy.
