The point that she has no dice for [RANGED] makes me think that even though you are performing [RANGED], you are using all of the [MELEE] symbols on her card and dial and pretending they are [RANGED]. You can’t just treat the dial as changed, you have to temporarily change the icon for the melee dice. If you do that, why isn’t the surge effect changed as well.
If you counter by trying to argue that you just gather all the information for a [MELEE] and then perform a [RANGED], why isn’t the surge effect information gathered as well?
That would make the surges work.
I would then then have to say that you treat it completely as a ranged attack and Cover works
