Why would you want to do that?

I've been tempted to do it the other way around, though. In a hosting  
environment, you can end up with a bunch of /24s dumped on a  
broadcast domain with a number of different customers but the  
addresses so intermingled that you can't give each customer their own  
VLAN. With IPv6, there is enough address space to give each customer  
a VLAN and and address block to go along with that, which is a lot  
cleaner.
