The way I look at it, is from 1 1/2 diamonds over from the corner (measuring from the same corner that the side pocket is), anything on that line or inside will not go "consistently" in the side pocket.
I just use that as a rule if shapes are needed and do not shoot it. If anything it is about as reliable shot as trying to purposely scratch in that pocket on the shot you described.
I agree with the Doc. 5 in the side is risky. Plus, Skunk had no plan for the 1.
I'm having a hard time picturing the angle on the 4 to the corner. If I can cheat the corner to the left, this rack is easier.
Looks like the corner pockets are generous and have shallow throats, so I'm saying the 7 passes the 13 clean and/or catches enough of the far pocket point to roll in if hit softly off the side rail at <1/2 diamond up side rail.
SAFE OPENING 1: A pretty strong opening safe would be calling the 4 in the corner and rolling the CB barely into the 5-7-13 mess. CB will likely be in double kiss range of the 13. The return play to avoid a foul would probably alter the layout significantly, and my crystal ball gets cloudy.
SAFE OPEN 2: Play off left side of 1 ball and position cue as close behind 10 as possible. 1 ball should move to side rail. Incoming player has tough 1 bank, or a shot on the 10 that goes nowhere.
GO FOR IT:
1. Pocket 1 with low inside kill. End up with CB even with start position but 12" closer to bottom side pocket.
2. Pocket 4 with follow and cheat corner pocket to left. CB follows into or thru 13, moving 13 toward left end rail middle.
3. Should have shot on 7 or 5 into upper right corner. Other one goes in upper left corner. Key here is to return CB to middle of table after this 2 ball pattern.
4. Then, it's 3 to lower left corner, coming off left side rail for position on 2 into upper right corner. Soft follow for position on 6 to bottom side.
5. 8 into upper side, upper right or bottom right corners.
Only touchy steps are #1 and #3.
Keep them coming.
