I'm having a heck of a time trying to make a 4-pointed star geometry ship, with the cockpit in one of the arms, with an even symmetry. The biggest challenge is, when using the 1x2 pointed slopes, getting the 'armpits'. I don't think there's any compatible inverted corner pieces. Any ideas? Or perhaps getting Keen to update the armor block shapes...

Here's an example: https://dejpknyizje2n.cloudfront.net/svgcustom/clipart/preview/star-2602-13864-550x550.png
