not really. to some, floyd rose is just a gimmick. sure, there are plenty of nifty effects that hanging bridge adds, but beyond those tricks you won't get any more constructive. You can wham w/ a normal bridge, just no higher pitch shifting.
and whoever says lower tunings != FR is joking. FR-equipped guitars are the most convenient to have a permanent tuning different from the standard ones. Hell, you can tune it 10 steps down practically and you'd still feel it's normal.
