The only question is how big a hurry are you? If the answer is "not much" then by all means do it! Remember that there will be many decisions like this one as you work your way through the rebuild/restore, where this will only take a few days you will multiply this by all the other total tear-downs and you could be looking at three years, maybe more; I'm living proof of this. Sometimes I wish I had taken a few shortcuts but I know that when it's finished I'll have do regrets, at least not about doing a thorough job.
