I do not have any issues with the springs clunking when driving. If you put 1 or 2 inch shorter shocks (depending on the drop) you could stop the suspension from dropping too far. The only issue you might have with shorter shocks is getting the tire out from under the fender.
I tried using drop limiting chains bolted to the frame with 2 inch drop springs to keep the springs from falling out. To keep the springs from falling out, they were just a little too short to allow the tires to clear the fenders when changing them.
