Allowing evil outsiders to then become good (which is a prerequisite for being a paladin) means you've already houseruled them enough that that particular rule doesn't make any sense any more.
Except there are canon Fiends who aren't Evil, which wouldn't make it a houserule....plus, the general statement "Always Alignment X" only means that an overwhelming majority of the population is that alignment, not that the creatures are actually "Always Alignment X".
