this is a bad idea because mudra cooldown currently does not start until you have used your ninjutsu.

lets say you use ten, spinning slash, chi, gust slash, jin, aeolian edge, ninjutsu. this leaves you delaying the use of your ninjutsu and effectively prolonging your cooldown, and by extension, decreasing your dps by a good bit.

if youre really having that many problems with mudra, you should just use Fuma Shuriken instead of raiton
