I think you may be biased by the fact that you got lucky with the kick. I agree it's a pretty high percentage hit on the 5, but I don't think it's high percentage to get out or get safe with it.
I think the high percentage shot for staying alive another inning is to nudge the 9 very slightly out of line without giving up the carom (as others have suggested).
Nice shot, by the way; must have demoralized your opponent.

I'd go with nudging it out of line and giving up ball in hand. Kicking at it is a possibility, but as it was stated in the beginning, because of the way it's lined up, and the balls aren't touching, it could go or it could rattle in the jaws. I don't know about a lot of you guys but I tend to not take a chance on balls that "might" go. I'd rather be 100% sure it's going and find out I was wrong than think it might go and end up finding out it wouldn't. In a situation like this, contacting the 5 isn't the problem, it's if that 9 will go or not. As for giving BIH to a strong player that means absolutely nothing. You have to do the best that you can do to get yourself back to the table. Winging at that "might go" shot isn't the best way to do that. Nudging them out of line and giving up BIH is the way to go. Worst he can do is play safe again, and that means you're coming back to the table. I wouldn't take a winger on any shot until I was on 2 fouls.
Now, since we're talking strength of game, and since everyone here always seems to get out, make fantastic shots, and can do things mere mortals can't think of, how about this one. Control the speed of the bank on the 6 and roll it up behind the 9-5. Or bank that 7 across table in front of them. Hey, if you have the nuts to kick 2 rails at a "might go" ball then what would be so out of line with the banks to block both of them?

I'd nudge out of line though
