Um, I don't think there is actually any system like that available for FPS Creator yet, would definitely be an awesome addition though I can certainly see where you're coming from.
With the right programs and scripts I'm sure you can easily create a sort of barrier system much like it, there's many great free modelling programs out there like Blender for instance -

And the basic script you'd need for this, as in something where a board came into contact with an enemy, it broke and you could in fact, in a sense "re-build" it could maybe tie into the "money system" created by Conjured Entertainment -

Perhaps through some tampering with his scripts (with his permission of course) you could somehow alter it to work for rebuilding a once broken board (which would re-appear in place I guess) for a particular amount of money?
And there is a fantastic thread to help people learn to script -

Not sure if this helped at all, just trying to point you in some sort of direction; and namely away from asking people to just give it to you. Hopefully this has some use to you, would love to see anything you might create with this idea in mind man
Cheers!
