Hi ew...
No, technically the intervals would be an octave apart (between 9 & 2).

A true ''2'' chord with the root in the bass would have some challenging fingering options in standard tuning...because it would include the root and the note one step above it then the third and fifth...much easier to play clusters like these on keyboards than guitars...

And most chord tools don't list the ''2'' muchless the ''sus2'' (out of 4 solid chord programs I own, only one lists the sus2 and none list a straight 2 chord in maj, or min, seventh, or dim configurations)
