I am not proposing a slavish devotion to Ripley. I am offering a counterpoint to the idea of having more knock-off female lead-roles. By not using Ripley, we end up with these stories with strong female characters that all try to emulate Ripley in some way. So to free us of this trope, let Ripley have her come-back film where she fulfills that female role, and let the other films be free of that trope once and for all.
Or alternatively, they could do something actually original and cast a male lead. It would be a very welcome change at this point.
That would be a really interesting thing to try out.
It's like Alien has female only leads and Predator has male only leads.

Maybe both franchises can do a gender swap and let's see how it goes from there.
Because let's be real, it doesn't matter what chromosome configuration you've got, the Alien or Predator will overpower you regardless. The point of a lead is to show us humans using wits and tactics to overpower them.
So whether it's a skinny man/woman or an AHNULD/AHNETTE type character, it all boils down to smarts and environment and luck in the end.
