Complicated!

Even more complicated!

Why not keep it simple and just assign each customer a 
/48. Or if you know that you are in risk of an HD ratio
problem then give consumer customers a /56.

Simple!

When new customers move into town and sign up with you,
their existinge equipment and home setup works just the
same as it always has, just the /48 prefix changes.
