Helll naw, 1010 - 15% crit, Mei - 40% Nin and Tai, Mei has way better buff and it lasts longer, and i am pretty sure she does more damage then 1010 as well, especially if you run Blood Limit boost not Fire Boost.
And with Iruka your clone should live 4 rounds anyway, so move him back to not loose Asuma buff.
Main Iruka Clone
Mei *x *x
Asuma *x *x
So Iruka is on +Atk and rest are on +Nin for max damage if you use first tactic.
