I made a pair of identical twin OC's, and gave them very similar but not quite the same semblance. The way I figured is that your semblance is also based on your personality, and even if identical twins are the same biologically and very similar in personality (though there are quite a few identical twins I know of with vastly different personalities), they would still have minor differences to their semblance due to the minor differences to their personality. So a twin who is brasher than the other would have a more physical semblnace, whilst a twin who is more of a thinker would have a more stealth/scouting based semblance. Two sides of the same coin, as it were.

It would be a very rare occurence for identical twins to have the exact same semblance, due to the different ways personalities develop. this, although I'll attribute it to personality being altered by their experiences (or Nurture for the psychologists).
