Out of interest, why the BVI in particular, and why a live-aboard? I'm not contesting the choices, just curious.
What I've read about the Cuan Law in past threads suggests it's got some non-diving things to do; not necessarily the 'eat, sleep, 25-27 dives in 7 days flat' scenario I associate with Caribbean live-aboards. And the BVIs have beautiful beaches and some topside scenery, IIRC? In other words, unlike Little Cayman and Belize's Lighthouse Atoll region, it's not so much 'all about the diving.'
So your post has me curious as to how you came by these 2 goals. The answer might help shed light on whether you'd be better served by a land-based BVI trip, or a live-aboard elsewhere.
