If you can't zero them separately, I really don't see much of a point. I'd rather have one dot and deal with y holds from there. Here's some number on black tip from a 9" and 16" barrel just to give you an idea of the trajectory.
Subsonics will be quite different and while the bottom dot may get you close, I can't see it being a real benefit.
300blk Barnes 110gr TTSX Black Tip .264 1,300fps
Velocity - 9" 2,120fps | 16" 2,390
Expansion Threshold - 9" 335y | 16" 430y
Trajectory with 50/zero
9" 50/135z | 100y +0.9" | 150y -0.9" | 200y -5.5" | 300y -26" | 400y -65"
16" 50/170z | 100y +1.5" | 150y +0.7" | 200y -2.4" | 300y -16.8" | 400y -45"
300blk 220gr Sierra 220gr Subsonic .72
Velocity - 9" 1,020fps (16" will be similar)
Expansion Threshold - N/A
Trajectory with 50 (peaks at 50, no secondary crossing line of sight)
9" - 75y -2.2" | 100y -6.5" | 125y -12.8" | 150y -21.6" | 200y -46" | 250y -80" | 300y -123.7"
For me, a standard EoTech reticle would be more useful than a blackout reticle.

Proven combat techniques may not be flashy and may require a bit more physical effort on the part of the shooter. Further, they may not win competition matches, but they will help ensure your survival in a shooting or gunfight on the street. ~ Paul Howe
