I went from VP100 to VP180 (with M60s) so my experience won't be quite the same... but IMO since there's only one center channel it's a relatively less expensive upgrade than anything else, and the center channel seems to do quite a bit of the heavy lifting...

So yeah, I would upgrade unless doing so meant I had to seriously downgrade something else.
