I like the idea but

 

look at where mahle is puting their struts on modern designed pistons
 
I do like the middle high & tight like you have I think of the piston swinging around in there like swinging a bucket full of water in a circle, the most pressure is going to be in the very bottom. It also puts it opening above the reeds so they dont impede flow. I also vote rounded hole edges , nothing square or triangular as it focuses load. Just my 2-cent, from one who doesnt know

Well, we have a 3 window design......the teeth are low enough to close off the intake as the transfers open up...........I think we found a final design that will work!!
