Trying to create a Kotlin Intention

Inside my intention I want to create some code that is valid Kotlin but not valid Java.

override fun invoke(project: Project, editor: Editor?, element: PsiElement) {
  val factory = JavaPsiFacade.getInstance(project).elementFactory
  val softly = factory.createReferenceFromText("ablock { }", null)
  element.replace(softly)
}

I'm guessing I need some kind of Kotlin factory but I can't figure out how to get one.
