So in case anyone else interested in this issue, I found the key for my situation.
There are devices that will lock to SMPTE reference and create a word clock for audio gear. A couple of devices came up on my trolling (mostly on gearslutz.com) which will slave to house reference or can generate SMPTE reference. Not sure yet which will operate locked to video AND generate clocks faster than 48k.
Rosendahl’s Nanosync & Nanonsync HD (which can generate tri-level sync for HD)
Aardvark’s Aardsync II
Lucid SSG192
Isochrone OCX-V
