I think Kaje's already doing some horizontal log-type bricks so you'll probably see those soon. I'm focusing more on inverted corner pieces.
Why do I keep working on the exact same bricks as you? This is starting to be a little freaky :tinfoil:

All they need is Brick Icons, everything else is exact to the point that they match the current ramps in all UV coords and in Collision. I have 45 degree ones too but I didn't make those up from scratch, I got them in Space guy's add-on.
Also these aren't props, and you can therefore have a forgetton of them with minimal performance impact. Case and point, here's a brick with a decent amount of Quads (Not Mine):

I get 18 fps with this, which by all account on this crappy 2004 laptop is quite good. You can't do this with Doors assuming you removed the restrictions.
Fake edit: Love the wedge brick ^^^
