I'm in a similar situation, thinking about a paycut or sabbattical just to do something different.

I think it's key to think about what makes you happy and interested in your work, and then find a way to map from your current position to a new position where you can do more of that.

If you're ever unsure or worried about making a move, remember that life is fluid, things change, doors open and close all the time. Taking a step forward into the unknown will light the path to the next step, but taking that first step requires accepting some uncertainty and trusting it will work out anyway.
