Bob, Thanks for your repsonse. I know the highway department typically does not grout below the baseplate. My challenge with this situation is the bolts are set and the heights can't be adjusted to fit a nut underneath. Since I don't now much about the original steel, welding a bolt extension is probably not wise. I probably can get about 3/4" grout thickness out of the present situation. It puzzles me that if double nuts are a better design why it is not done. All of the lights I observed had grout below the baseplate. Some grout pads were up to 3" thick.

There must, of course, be double nuts on the anchors and the protuding part of the anchors must be kept short enough to limit anchor bending, but ungrouted baseplates are common.

I'd add that it is very easy for grout to be placed poorly under a baseplate. I do not know how one would pressure grout in a way that ensures that the entire area of the baseplate is filled, especially with such a thin space. I would not regrout with the pole in its current position.
