To force the assignment of a new IP address, the
ISP would have to kick the PPP session. Most
routers will re-establish automatically, and pick
up the new address.

If the end-user isn't using the connection
heavily, they may not notice.

Oh, but you could...

Quick change to RADIUS attributes, kick PPP,
router re-establishes with new static address.

It's considered bad form to do that without
informing the end-user, of course. However, it's
sometimes necessary - during a DDoS, for example.
ISP can't block the source, so drops based on
destination, then punts end-user onto a new IP so
that they still have Net access.
