I couldn't find anything on Hull Wedges being built upon one another like this, so I'm placing my suggestion here.
Unfortunetely the current hull wedge block stats would have to be modified so that all armor doesn't become two wedges placed together, and the block ID system would have to be modified to either hold every combination of 2 color hull blocks or be able to handle more than one block in the same square. This new system would allow us to complete more complicated designs and decorations on our ships, and help beautify our systems.
