if you have screw on rears, then you won't have the lock ring thread to hold the fixed sprocket on- ok on the track, but not on the road.
The fixed axle width is narrower than a road axle - it only needs the width for one sprocket where the road requires more for "x" number of sprockets. That in turn will mean the dishing of the spokes is in need of being reset to get the rim central on the hub.
All in all a lot of faffing about that can be done, but buying a new rear fixed wheel will neatly avoid, although it will leave a hole in the pocket
