I just looked at the pics again that should be fine, for some reason I thought there was more rock against the glass than there was. Yeah narrower tanks suck to scape. This is all from experience my 29 (my first reef tank) was just a rock pile that touched three sides and was always kind of a pain.
Haha yeah I figured a 29 would be a PITA so that's why I'll be setting up a 20 long over the 29
