That's quite the spread of lenses to test, godspeed. Particularly interested in seeing how well the Tokina does. If money wasn't an issue, I'd love to test some of the newer players in the astro realm, specifically:
Tokina 20 f/2
Rok/Samyang 20 f/1.8
Sigma 14 f/1.8
Laowa 15 f/2
Unfortunately astro plays second fiddle to most types of shooting, so I've seen inconclusive or nonexistent information regarding sharpness, vignetting, coma control, and chromatic aberration control for these lenses.
Yea I'm going to be ambitious . We'll see how far I get.

EDIT:
lenstips.com has the sigma reviewed with coma even at 2.5.

I guess I could add the Samyang 14mm 2.4 and Sigma 14mm 1.8. It's not too hard to do these really. Setup the tripod, switch lenses, shoot some frame. Hardest part will be to keep track of all of them . Oh and the rental fee. Maybe Roger will help me out if I write a blog column for him 
Here's my check list:
- Vignetting
- Sharpness wide open or close
- Coma
- Relative brightness
For comparisons:
Sigma 14mm 1.8 @1.8, 2, 2.8
Rokinon 14 2.4 @ 2.4 and 2.8
Rokinon 14 2.8 @ 2.8
Batis 18mm @ 2.8
Tokina 20mm @ 2.0, 2.2, 2.8
Loxia 21mm @ 2.8
Batis 25mm @ 2.0, 2.2, 2.8
Rokinon 24mm @ 1.4, 2.0, 2.8
