The Xen hypervisor also got many of its design elements from the Nemesis OS, which had a lightweight kernel. There's plenty of overlap possible. A number of research and production systems are also both hypervisors and microkernel-like, too. So, it's more an existing concept than a bizarre, hypothetical connection. For OKL4, also deployed in over a billion phones they claim.

NOVA is an open-source micro-hypervisor available in GenodeOS that similarly combines hypervisor functionality with a microkernel-like design:
