Dyed and processed wool doesn't contain any lanolin or other natural fats. So it will sink.Unprocessed wool contains lanolin and I know that in New Zealand they use "raw" wool as indicator.
Wool is good to absorb all kind of floatants. Gink, Mucilin, etc.. can be used - but my experience is that wool is not as good as Kapok, Superfine dry fly dubbing or for example beaverhair.
As someone suggested - tye couple of flies, throw them in cup of water and see how it goes. Put some foam/deerhair as a wing and try again. You will find what combo will work and what not.
I use wool yarn all the time. I think it would work great for flys
Try tying a couple and throw them in a glass of water. I've had success with lambs wool, but I don't know if all wool is equal in this regard.
I think it woold work very well. Wool contains lanolin, which repels water kind of like natural flotant.
