My main concern would be if the new 8' listening distance gives the drivers a chance to gel together. If memory serves the drivers in the Rev3s are somewhat far apart, so this may be an issue. If you experience a lack of coherence between bass/mids/treble you may need to back the speakers up closer to the wall. It might not turn out to be an issue at all, but it would be something I'd watch for.
