I think this fits what you were after?
Can't hang a block on the sides.
Supports blocks above it, but if a lower one of these is destroyed, any "NoGlueiBeamCentered" above it collapses.

Couldn't get the stock iBeamCentered icon to show up, so used a pillar50 icon & tinted it dark red.
The 'ghost' preview shows the i-beam as it should.
Since you've already made a bunch of modlets I figured the file contents would be more useful, and save you a download.
Hope this helps
