Hi Randy, this variety of ficus should put out aerial roots fairly easily, especially on an old tree like yours. If I could get it to grow in Southern California, then anybody could do it. Do what everybody else does, just put a wall of some kind around the trunk and high branches and fill in the space with some loose materials like bark mulch or pumice, then water it well, then watch them roots go! Your winter will set it back a bit, but the mulch can keep it warm too. There are some pictures of this procedure on here somewhere I believe. Do a search and see. Here's a picture of one of mine I posted 9 months ago. It had put a lot more aerial roots this summer. I just don't have a new picture of it.
Actually, looking at your tree again, I think it would be good as a tall informal upright too. It has a few good curves on it. There's always more than one option.
Good luck!
Si
