So if I'm reading this correctly you want to put another fielder (in this case the SS) somewhere near the plate area and throw to them.
I see a couple of problems with this
1. The other fielder (SS) will be in foul territory and all fielders (with the exception of the catcher) has to be in fair territory at the time of the pitch.
2. For it to be a pitch it has to cross the plate or foul lines so if you want to put him in front of the plate or up the line to try and satisfy number one you now violate this.
3. If we're talking NFHS rules or most other rule sets (not all mind you) for amateur baseball you don't have to pitch to the batter. All you have to do is say "put him on".
4. Like Jimmy said - you're going to interfere with the batter and / or put the fielder in harm's way.
5. Like JH said - a pitcher should be able to put the ball in an area for a pitchout to intentionally walk a batter if that's what the rule set requires. To do anything else would hinder their development to move on in the game.
This is just not a good idea.
