that is what john byrne did during his classic (and title saving) run.
he pulled sue to the front and made her the most powerful of the FF.
she went from "invisible girl" to "invisible woman" to all powerful "invisible PAWG"
sue stopped the hulk after all. none of the others could do that.
(john byrne + claremont did the same thing with the x-men. notice that in general x-women are more powerful than the x-men - storm. phoenix, polaris, binary, dazzler ... )
"The Invisible Woman received her powers after cosmic radiation had triggered mutagenic changes in her body. Originally only able to turn herself invisible, Sue later discovered she could render other things invisible as well and project an invisible force field. It has been said on numerous occasions, including by the Fantastic Four's greatest opponent, Doctor Doom, that Susan Storm is the most powerful member of the quartet and one of the few beings able to rupture the shell of a Celestial.[45][46]"
"For example, Sue can shape her fields into simple invisible constructs or generate a nearly indestructible invisible force field around herself or her target. She can vary the texture and tensile strength of her field to some extent, rendering it rigid as steel or as soft and yielding as foam rubber; softer variants on the field enable her to cushion impacts more gently, and are less likely to result in psionic backlash against Susan herself. She is also able to make her shields opaque or translucent like milk glass to effectively block variations of light such as laser-beams, or make them semipermeable to filter oxygen from water though the latter is mentally taxing. She can generate solid force constructs as small as a marble or as large as 100 feet (30 m) in diameter, and her hollow projections such as domes can extend up to several miles in area.
By generating additional force behind her psionic constructs, Sue can turn them into offensive weapons, ranging from massive invisible battering rams to small projectiles such as spheres and darts. By forming one of her force fields within an object and expanding the field, Sue can cause her target to explode. She can also travel atop her animated constructs, enabling her to simulate a limited approximation of levitation or flight.[50][4] She can manipulate the energy of her force fields around other objects to simulate telekinetic abilities as well. She is capable of generating and manipulating multiple psionic force fields simultaneously. This power is only limited by her concentration; once she stops concentrating on a psionic force field, it simply ceases to exist.[citation needed]"
