Mono (and RP and polynerdist), if this feels right - if it's something that all three of you are comfortable trying, then why not?
You three have a very open communication process, so I am sure that you will take some time to work out some of the practical basics and "what will change".
The other thought is that if it doesn't feel right once you have tried it, what is to stop you going back to how it is today, if that works out better?
If you make it a low risk proposition then people can relax a lot more and see what works and what doesn't rather than making it a Big Step that people need ot be on edge about.
