Yeah, it even works better generally than defensive-oriented shields in this particular build.
This build has a lot of passive damage: Return Fire (which triggers Smite occasionally), Superconductor, and Asteroid Belt. Along with grenades, there are plenty of ways to deal damage and thereby heal yourself without worrying too much about shooting constantly, such as to build and maintain the Continuous Damage bonus (which isn’t very large anyway.
I think people underrate passive damage. The reason my Sal Mob build was so easy was because of its passive damage and healing. It happened to have DPUH Money Shot Chains too.
Asteroid belt frequently steals my kills in both this build and my Nisha build…
