No, that wouldn't work. Even if you did something like run double Avant lead + iST-SBB, you'll still end up killing the main body before the specific part, even if you never triggered the crit buff from any crit buffers. Even if you waited, it would depend on your team's squad. If they brought a crit buffer, the run pretty much becomes wasted.
