A 30″ x 30″ base 90° module would be too small for the hinges and doors to operate correctly. It would also provide an opening that’s too limited to be useful for storage. I recommend using a blind corner cabinet in that area and allowing the filler to span the 6″ wide gap. We can certainly increase the width of the filler on the face of your blind corner cabinet, as long as this is noted in the order comments at checkout.
