The greater potential for damage at floor level made me review the pedalboard idea. Even with it under polycarbonate (indestructible!) and surrounded by ply its still on the floor where someone else could do something really stupid to it, hence the small rack.
I think the pedalboard concept will work and I may still do it one day, ultimately that decision may be influenced by the kind of environments you play in.
Out of interest, what are you wanting to achieve with your gear?
