Right click to color-pick?

Hello, I know you can change the keyboard commands, but is there any way to change the right click function of a tool?

I like to color pick a lot while I'm working but I find alt+clicking clunky and I'm used to many other programs that let you color-pick by right clicking which i find much more useful and streamlined. I really don't need say the brush selection panel pop up while using the brush tool, since I rarely change that.

Also, is there a way to make a brush erase instead of lay color (ie. instead of switching to the eraser tool, have the brush tool your currently using remove color using its current settings)?

Thanks!
