Well, others will disagree with me, but RB67s and Leicas are a lot of camera to be using with Epson flatbeds. If it were me, I'd either be upgrading my scanning/printing game (e.g., professional scanning, darkroom printing, etc.), or downgrading my film camera kit.
Cameras are only one piece of the puzzle in film photography, along with light, film, tripods, the scanning/printing process, and, most importantly, what you bring (e.g., creativity, composition, etc.). If people enjoy one piece of the puzzle (e.g., camera gear, darkroom process, etc.), there's nothing wrong with that, but film photography ordinarily requires tightly coupled consideration across many of these areas to maximise output (this isn't referring necessarily to resolution). For instance, I like using my Lomo LC-A 120 and Holga, but I will make different film, scanning, and printing choices to accommodate the strengths and weaknesses of those cameras than I might with my Plaubel Makina 67 or Rolleiflex. Likewise, if I know I'm only printing a picture to 5x5 or I'm scanning it at home instead of using a pro lab, then this impacts my choice of camera.
