This is the sort of the Bastion rules can address -- the PC doesn't need to craft things if their bastion can do so), but even still, it comes online too late for most non-magical items.
The Bastion playtest attempted this... and it was REALLY BAD. Like, insultingly bad. The Smith shop option for the Bastion had a list of items that you could choose to make, and each item took one week to create. Or, if you were a blacksmith, you could yourself make the entire list, almost twice over, in the same amount of time.
They also allowed you to spend 3 weeks and 800 gold to make a masterwork martial weapon, which could then have Magic Weapon cast on it to make it a +1 weapon... with a value no higher than 500 gp.
The Bastion rules are a good place for crafting rules to be worked into the game. But they need to be majorly overhauled from what we had initially seen.
