Given the situation and the limitations you have, your list is fairly complete about what can be done. The previous mention of adding a mass bag of some sort on top of the lens could be helpful. I find that using your body to block from the up wind side can be a big factor, and if you could find another willing person, their body may help on the down wind side. The key thing I have had good luck with is to time my shots to just after a lull in the wind. I know you will not have a big time window to work with, but still, most wind has lulls and peaks, so try. You want the camera and lens to have a second or two after a wind peak to dampen out some before an exposure if you can get that. And it may be obvious, but taking a lot of exposures should also help improve the chances of some being the best quality. And for any weight you add to the bottom of the tripod, keep the weight dense and hung as high as possible, so that it does not have as much movement with the wind.
For what ever you do, you can do some advance checking of how things are by going to live view, and setting the magnification to maximum, and focusing on some high contrast subject, and then looking at how stable things are on the screen. You can try tapping sidways on the lens a little to simulate wind, and then seeing differences with things like adding a mass bag on top of the lens, or changing what you hang from the center of the tripod.
You did not mention about trying things in the days before your best chances. I would suggest you do some dry runs that will allow you to understand exposure issues, so that they will be perfect. It is really easy to blow out the details of the moon in any moonrise or moonset shot. And if you believe in doing exposure combines, you may want to take some shots that expose the moon perfectly, and then some with a longer exposure that shows the sky and the hills better, and then combine them in post processing. Because the moon will be moving in the frame, you need to do a more complex combine, but if the sky is uniform that is not too hard.
By checking out things in advance, you may find locatons available that have less wind effect, but still allow a good foreground and the same distant scene. The weather may be different on your actual shooting days than the advance checks, but the more experience you have with possible locations, the better chance you will have to pick the best one for the real shot days.
And thank you for the reminder about this full moon. In my location, a full moon moon rise over our local snow covered mountains is something I need to try, and our weather has been unusually good lately. I may just need to go scout a place and be prepared to roll the dice with the weather gods.
