I added two backer levels:

$10 lets you choose one building from this list:

Tall Tower

Short Tower (this will include the balcony optional part)

Watchtower

Bunker

Barracks

The second at $20 will get you all of the wall sections, including the Gate Statues.

Hopefully this will add some flexibility for backers to choose from.
