Natural tendency on gear forums is for every one to tout what each believes and does as a solution for your (the OP's) individual conundrum. As John says, "bias by preference." Good way to generate ideas, bad if you start to discriminate among them lacking a healthy dose of your own experience and needs.
Seems quite reasonable, having concentrated all your resources into a one-camera/one-lens outfit, to experience some doubt. But, fact is you developed a plan. Carry it out long enough so your nagging doubt is eliminated or confirmed. Then you can make a clearer decision. Another digi M, a different digi M, non-M digi body, a film M, a non-M film body - all these ideas have merit. But they have to become yours with the benefit of some experience or you will just end up playing gear roulette.
Good luck and have fun with that lovely camera.
