Removing overlapping objects, made with particles I have some "bricks" that I put on an object with the particle system, but many of them are overlapping. 
I could use "random size" in the particle menu, but i want to keep the bricks somewhat uniform size.

Is there a way to avoid this with any of the options in the particle menu? Or, maybe after converting the particles to meshes, would it be possible to remove the overlapping ones ?  

It is a static scene, no physics are involved.
go to emit from tab in particle system settings (you have to have the advanced checked), there you should have selected faces by default (if you didn't change it), then select one in particles/face.
Before:

After:

Faces:


If this doesn't work for you (you have too small faces or something) you can convert the particle system (mdifiers - particle system - convert) and then delete the overlapping bricks.
