Sure -- though many ISPs will probably let you keep the address space, 
even if you switch away completely -- as long as you pay them enough 
(or the other ISP to route it).

Bad practice, but has happened a lot, and probably still does :)

FWIW, even if you are multihomed, that does not in and of itself
require that you "own" address space.  Public AS number is often
enough (and even private will do, but that leads to other kind of
mess.)
