If you actually wanted to fix things your nin opener could have one advantage over the standard trick window wise.

You need to delay pot, mug, kassatsu one gcd. This shouldnt cause any problems because you literally have the extra gcd in front of those 3. Bunshin at the same spot to keep more hits in pot window.

Delay dwd and bhava after shadowfang. Unfortunately this means dwd will be a more awkward weave in later tricks but it would be how to make it optimal.

Right after hyosho > dwd, > raiton then tcj > meisui so you can keep that tied to tcj without ninki overcap. Additionally this would lessen the raiton overcap by 6 seconds.

Then gust slash assasinate raiton bhava finish your windows.

There are still other problems like i said with delaying trick till 15, but if you really wanted a nin to do this the above is how it would as current knowledge stands be best accomplished.
