can green wood be stabilized with cj?

No, you can not stabilize green wood, the wood needs to have a maximum moisture content of 10%.  Oven dry (0% mc) will give the best results.  Green wood is saturated with water and has very little air in it.  Stabilizing displaces the air in the wood with Cactus Juice by "removing" the atmospherically compressed air with vacuum and then filling the space that was filled with air with Cactus Juice when you release the vacuum.  Since water is not compressible, vacuum is not going to easily remove the water from the wood and as a result, you will get very little resin back into the wood.
