Try a 45 toward the trap, and reduce the slope on the trap arm (after trap) to 1/4 inch per foot until you hit the vent.

For space reasons, you might want to stay with 1.5 until you are past the sill. But if you have room, you can go from 1.5 up to 2 at any point. A 2 inch trap arm can go farther before it needs to be vented.

I am not a plumber.

I would not feel good about inserting a glued piece into a fitting that does not make it to, or very close to, the stop.

You can do the "running" trap.

Great. Thanks Terry.
