That will work. I use less coconut oil and more tallow, but there isn't any reason not to try your recipe.
I would put the EDTA in the water for the lye, and would use 0.1% or more. I've also had issues with rancidity in my shaving soaps, so I now use 0.1% citrate and BHT in everything. May or may not be an issue with tallow for you, but something to think about.
Home made shaving soaps last a very long time for me, be careful not to get too excited and make a couple pounds of various experiments like I did. I won't need any more for about a decade.....
