As I have experienced an inability (or signficant difficulty) in connecting QCs at time (for the reasons given)
my only advice to you is to go through your switching scenario and assume you cant hold your breath long enough to connect your QC.
By using a BOV your adding more failure points (the bov each QC and its hose), more complexity and more risk but the upside is your likely to have higher wob...no wait thats not a pro...whats the pro again??
