I think that would be unnecessary. The only thing you need to get done in the primary fermenter is the majority of fermentation. Once airlock activity quiets down to virtually nothing, there's no need to just leave the beer in there unless you plan on foregoing secondary fermentation altogether (i.e. filtering prior to kegging and want to allow time for full fermentation and flavor maturation).
If you're doing a secondary, there's really no need to leave it in the primary for 3 weeks.
