I like the thinking. I would ask you (if you were my teammate) to take cueball in hand and line up where that cueball needs to land for the 13 in the bottom side, and then place the cueball to each side by an inch and see if it’s still good. Feels like the the 5 and 3 are in play if you don’t get exactly correct on that 13 line. Considering you’re thinking if you come up way short that your bailout is to the left bottom corner, whereas I’m asking if you miss your line by an inch. It’s just another reason I like to avoid the side pocket in 8-ball if that angle is crucial to the out.
Now that I look at it again, I'd probably just play 2 rails for the corner IF I went the 11-13 route... which as I said in my original plan I'd just avoid and either shoot the 13 first or as key ball naturally landing on it off the 10.
A collision with the 5 is very likely when playing for the bottom side and to avoid it, you'd have to be just about as precise as going for the top side. Opting for the more difficult corner shot coming off the long rail with the CB, you can be short, long, or miss your spot on the rail by a few inches in either direction and still be fine for getting on the 14.
But again, these considerations are exactly why I avoid the 11-13 route in my plan for the rack. I just think 13 first or last are both higher percentage outs with fewer shots demanding a high degree of precise line+speed.
Even with my preferred out, the 11 to 14 is no picnic either, but the position area where you are fine getting from 14 to the 10 is massive and you can probably even get away with most incidental contacts with a solid on the way there.
