I mean it's all about counting up the steps from the root right?

It looks like you've already figured out the sus2 is possible on guitar. :)

But just for a little further clarity. You are correct that the 9th degree is intended to be used in the context of "higher than the octave of the root". But it is generally accepted that the 2nd & 9th scale degrees are interchangeable in some contexts regardless of octave position. Often a chord is labeled sus2 even if the 2nd is in a higher octave.
