Sounds very possible. Use the audio jack to connect to the PA and plug the hdmi output into a projector.
My Pi Presents (see sig) will allow you to make shows of the videos and to redirect the sound to the audio jack.
I did try it once myself, very quickly. It worked but the projected output was very small. I suspect this was because the projector had a smaller resolution than my monitor and I would need to reconfigure the Pi (config.txt).
