I see what you are doing there, but I would advise against changing Ponta's handling that much.
The reason why his quick matrix works well, is be cause it is quick, and all of the transpos apparently happen at the same time. But using the same handling he does in his quick matrix, and showing the transpos one at a time, doesn't really flow well.
I would suggest getting down his quick matrix as it is first. Then, work on his regular matrix routine (slower versions). Once you can actually do those well, without fumbling, then you should think about creating your own version.
But you should really work on the routines he has provided first so that you can understand the subtleties better. Trying to change them too quickly, and you will be left with facing obstacles that you don't realize exist. Like, "does this flow into this?" or "does this routine theme warrant the use of these sleights?" etc...
