Obviously the shape isn't ideal, as I should round it slightly and especially round the corners, but as a proof of concept, this looks promising.

 

I really like this shape in the bokeh. It reminds me of 1950s graphic designs.

If that's the direction you're going, have you considered a Blazar Mantis?  It's a 1.33x squeeze and has an internal oval aperture to give what they claim to be closer to a 2x bokeh look.  I've looked at them a few times and I personally find their bokeh to be a turnoff, but a bunch of people seem to like them.

Otherwise, it might be worth looking into whether any currently-shipping lenses allow a waterhouse aperture.  I had a modern Petzval for a bit that did.  If it's a waterhouse, you could put tape over the biggest and cut out any shape you want for the bokeh.  I think lensbaby have one or more lenses which have both a standard round aperture and a hole for inserting bokeh-shaping cutouts.  I might even have one around year somewhere from around 12 years ago that I've only used a few times - not for the bokeh cutout, but because the front element of it is on something like a ball head so it can be unlocked and moved freely around to get all Scheimpflug-gy(?).

The Blazar Mantis is an interesting lens, and does reduce the weight from 1.3kg down to 800g but the SB+50/1.8 is only 350g, so pretty hard to beat.  Plus the Mantis is probably 20-50x more expensive!  

The Lensbaby Double Glass has a replaceable aperture, but is 50mm F2.8 so on MFT equivalent to a 100mm F5.6 so pretty slow when compared to the Voigt+Sirui combo which is equivalent to a 68mm F1.5, or the SB+50/1.8 which is equivalent to a 71mm F2.6.  

I'm actually quite impressed at how much stretch and how consistent it was with the insert at the rear of the lens.  I'm guessing this is where a 3D printer would come in perfectly, as I could rapid-prototype a completely custom insert for it.  No matter, I'm sure I can do a reasonable job with some cardboard and a sharp knife.

I'd have to dig mine out to see what it is - but it's EF mount so usable on a speed booster.  🙂

(But still more expensive than cutting some cardboard)
