At 24k, anything is possible.
But I don't think I would. A peep at P8 should only induce Black to connect (same with P3) and Black can't be stopped from connecting their solid right wall to the top wall at P or Q (miai), and it also looks unlikely white will be able to stop Black from connecting the top wall to the left. (Directly cutting at P8, as you can see, would just result in a trapped white stone, unless Black foolishly ignores the threat...which is a possibility at 24k, but not extremely likely.)
If there were more cutting points in Black's wall, White might hope to threaten Black into defending long enough to put the foundations of an inside moyo in place. It doesn't look to me like there are enough weak spots in the wall for that. You couldn't expect more than three or four free stones.
On the other hand, since this is a beginner's game, playing at B19 may provide Black some fun and profit. If White immediately connects at C18, Black is totally out of luck, but if they play A19, Black plays A18 to capture on the corner: after that (or if White doesn't play A19) whatever other move White makes, Black should play C18 next, because if White plays C19 to capture (or if White plays C19 to begin with) Black can catch the D19 group in a snapback. (And if they don't of course, Black plays C19 and captures without a fight)
These little tesuji tricks are awesome killers when you're very low-level, but once you get to around 17-15k, everyone knows them and it's not so easy to scam your opponents. But I still occasionally catch some players with a snapback setup.
Edit: Of course, if white captures at F19, you might have a nasty little ko fight interfere with your plan: maybe you should settle that before carrying out your scheme.
, a "Great Moyo" game between two 24k.
