I was wondering the same thing myself about the scale. If you do give them a try let me know how you make out. Did you check out the tips section they had alot of good ideas for the do it your self types. Looks like a fun prodject with nice results and if the scale is off you could still use the nice stone floor pieces and some of the blocks for building walls. I found another site something like this one called Terra genesis with the do it your self thing, i,ll see if i can find and post that link also.
