I would say you're probably not ideally suited for Princeton as it is at least based on the players on the screenshot. While Murphy's passing is definitely a positive factor, the downside is that you're going to have to play another big man with either 2 or 3 passing along side him or at least as a backup when you bring in your new big man. Also, you definitely will want jump range and driving higher if you're going to run it - it's an offense where anyone can take a three or drive to the basket, so having those skills (along with passing and handling) represented in all five spots on your lineup is helpful.
The one advantage you might see from Princeton is slowing the game down some compared to motion and especially compared to R&G. It's also pretty good at targeting defensive mismatches if you have any. I just think you'd like to have a little more JR to be able to run it effectively, but certainly experiment with it to see if your experience is better or worse than expected. When it works, it's great fun and when it's off, it can be horribly off.
