Hi Zach,
In theory, the base shift should work for your case. But I’d test it first.
You need a point on a site with known coordinates in both ITRF2014 and NAD83(2011) to calculate the shift. Transformation between ITRF2014 and NAD83 isn’t linear, but within 1-2 km radius it should work fine. The radius is measured from the calibration point.
If you test it, please share your results with us!
