Wait . . . I'm not sure I understand what's being asked here.
Are you proposing putting on factory Rubi sliders on in addition to your factory side steps? Or Ace rails? That won't work. They won't fit together and are mutually exclusive. There also wouldn't be any point with the factory steps, since the steps are made of plastic and would break on an impact before the Rubi sliders or Ace rails had the opportunity to do any protecting.
If you're instead asking about using aftermarket steps with factory Rubi rails, that can be done with a few brands I believe, and ace seems to be the most popular. There is a very large active thread on here for ace sliders that has many, many pics of this set up. (Seriously--many pics. As in dozens.) I happen to think the slider/ace step combo looks better than the aces alone as well.
Finally, there are also a great number of aftermarket steps that incorporate tub armor as well. JCR, PureJeep, Poison Spyder all come to mind. That's the most protection available, though that doesn't seem to be what you're asking about.
