I'm not sure that this works regarding to RFC 3587 (sorry for the typo above)
"(...) also requires that all unicast addresses, except those that
   start with binary value 000, have Interface IDs that are 64 bits long
   and to be constructed in Modified EUI-64 format." 

By that I'm not sure, whether running an non-/64-Bit network is going to cause any side-affects. 
Is it possible to assign a /64 network on $INTERFACE when working in routed mode?

Eg  
ip -6 addr add 2001:470:780f::1/64 dev $INTERFACE 
ip -6 route add 2001:470:780f::1/56 dev $INTERFACE

Are there any pros and cons?

Keep smiling
