I agree with KO. I've bought almost every FS and Gothic mold and would definitely buy the 6" chipped stone tower and the 8" FS tower. The "odds and ends" mold is a must! Ruined versions of other molds would be great. More arches and arrow loops too. The number one thing I'd like to see is a FS basic block mold with nothing but blocks on it similar to #40!!!!! I only need so many skulls and sconces.

As for the FS octagon tower, HELL YEAH! I like the idea for the clad corners but would like to see plain ones as well and definitely include the expansion piece. Other ideas would be a FS and Gothic Hexagon tower also.

I don't think the onion roof would go with the FS, but it would definitely go with the gothic line.

Other things I'd like to see:

Round shale or shingle roof mold for the towers.
FS equivalent of mold 164.
The 60 degree splayed bases. (I have the tapered FS set from Kovax and they are great. If you could make a similar set I'd definitely buy the mold.)
Transition pieces for Gothic, FS, Cavern and Egyptian.
More Roman styled ones like the Roman Temple.

Whatever you make people will buy. ;D
