I had a reacher set up o
n my previous P19, but because of your reason #2 it had excessive lee helm. It was useless going upwind and difficult to steer on a reach.
Granted, this was a bastardized setup, with an old, used sail and a pole that was much, much too long.
You should be very careful going this route, as it is not easy to get the sailplan balanced. However, there have been several people who have successfully put spinnakers (with short poles) on N5.8's and P19's, basicially copying the I20-style setup. That is the route that I would recommend.
Note that you still have to ensure that your sail dimensions and sheeting angles are a good match for your boat. You will probably get much better results if you buy a new spinnaker cut for your boat's/pole's dimensions than trying to re-use an old one designed for a different boat (or even a monoslug).
Sail fast and have fun,
