Glass - can I use the same thickness?

I know it's considered "best practice" to use glass of differeent thickness in adjoining frames however I have stumbled across a source of 10mm plate glass that's FREE I was going to use 10mm and 8mm plate glass to keep up with my walls that are two layers of 5/8th one side and one layer of 5/8th the other side but this was going to cost me about $250 Would it be a huge problem to use this FREE 10mm plate glass on each side?. One of the panes will be angled as you can see from the attached photo. Thanks JohnG

I guess not. Your walls are a little less weight than the glass per m^2. So no problem, go for it.
