Ok, so after some testing, I have confirmed that additional Shadow Clones DO in fact boost the damage output of the Wind Main equipped with Queen's momentum. The issues that I run into is protecting those clones and the loss in damage due to using Shadow Clones over Gale Fan. The Shadow Clones don't combo enough to make up for that difference most of the time. In addition, I find that the damage from using Giant Rasengan and subsequent Rasengan - Shoot Down is only increased by a small margin, about 20% if I'm not mistaken. Therefore, in an era of AoE attackers and Hinata Tanks, I conclude that this setup isn't feasible to run in PvP.
