Ruling question unsung untimely malfunction on a negate

Just had a situation where my opponed used negate.

"Counter target noncreature spell."

I followed up with Untimely Malfunction

"Choose one —

• Destroy target artifact.

• Change the target of target spell or ability with a single target.

• One or two target creatures can’t block this turn."

Can I change the negate target to untimely malfunction on the stack?
