Given that both the CSXCV receiver and the Yongnuo YN-622c triggers operate using 2.4GHz, would it be possible to trigger Einsteins using the YN-622c as a trigger?

No. "2.4GHz" refers to a band of frequencies, not just one frequency. CyberSyncs alone have 16 different frequencies, all of which are still considered "2.4GHz" and one would not be inter-operable even with another CyberSync not set to the exact same frequency. So, they two systems would have to be on exactly the same frequency, which they may or may not be.

Additionally, to combat interference, CyberSync is encoded so that CyberSync signals are the only signals understood by other CyberSyncs.
