Changing Operator Gadget in Portal

Tl:Dr is Bold and Italicized 

Hello again. I am wondering if it is possible to swap the Specialist Gadget out for another Throwable or alternate Launcher Type. My current test is trying to change Sundance's Grenade Belt out for ×4 Incendiary Grenades. Any help or solid yes or no on if this is possible. I did have an "values are not Equal" earlier. But that was using Equals in a IF statement, guided by a Variable and then filterd by a subroutine. I think I got it wrong or way too jumbled.
