What would I see if I make a breakthrough between the two slits in the double slit experiment so it looks like a "H"?

Would the top and bottom part give the interference pattern and the middle part act like one horizontal slit so the light will show a line there? Or would the whole thing behave like one slit but with a weird form so I don't get an interference pattern at all?

It will depend on the exact geometry. If the breakthrough is thin then the result will still be dominated by the two slits and you get a slightly washed out double slit pattern. In general the pattern at the screen is the Fourier transform of the slit pattern. For the double slit you only need to care about one dimension which makes it easy to analyze, for more complicated patterns it's getting more complicated.
