D&D 5E Players, would you play in a multi-year campaign that used only the 5.1 SRD?

and i assume you all get your work skills from the same mostly predefined progression plan that you level up on at an equal rate?

Sure, but just like our IRL careers don't define who were are as people, classes don't have to define the PCs.

In 5e, I just don't think having multiple PCs with the same class is that big of a deal. You could give four players identical PC character sheet with the same class, level, backgrounds, skill selections, feats, and attributes. They can only fill in the name. It won't break the game and each PC can be very different based on how the players roleplay. It might even help the players get more into the roll playing if they don't have mechanical differences to use as a crutch.
