You might have a bit of extra work if you place the silpat on the Dobord, then roll out the dough. I think the Dobord is 15"x15", and if the silpat hangs off one side, you'd just have to roll more carefully. Since the height is adjustable, you can set it to accomodate the silpat and still get close to the thickness you want.
I got my Dobord from Cake 'N Crumbs...quick delivery, lowest price I could find on-line, nice service. I'm very pleased with my purchase!
