If you want to keep your motor in one piece you NEED a wastegate.
The wastegate is used so that the turbo doesn't keep boosting and boosting; as rev's get higher there is more exhaust so the turbo would spin faster. The wastegate acts to send the excess exhaust away from the turbo giving the turbo only enough exhaust to make 'X' boost.
The BOV on the other hand takes car of what happens during gear changes ect, when you change gears you take your foot off the throttle giving the engine less fuel so it slows down a bit, without a BOV the air coming from the turbo would be rammed into the engine (which is trying to slow down...) and slam back into the turbo (ouch!), the BOV vents the pressure created by the turbo to stop this.
If what your asking is "Can I only use a BOV and make it act as a wastegate as well?" I'm not sure, I would like to know myself!......sorry(just a guess but i'd say it's not efficient?)!
Cheers
