Anyone have any input about dying a grey coat?

The answer is no. As stated by several above, its not the wool, that is an easy dye, its the polyester, you cannot dye it, not at normal low temps, in the fabric industry they use special dyes and are done at extreme high heats and with chemicals, the side effect is that when you try this on a 50/50 blend it causes the wool to frizz or go fuzzy. But NO you wont get a black color on the poly ever...it may go a bit darker if your lucky but it wont take to black...I know from experience

You could try bleaching the coat before you dye it. Another idea is to take the coat to an upscale bridal shop. They'll have experience in dying fabrics, and will be able to tell you exactly how to go about the process, if at all. It might be easier to have a coat made in the color you want.
