I wouldn't replace restraints with displacements unless the restraint is linear. For example, displacing a +Y support downward 1 inch (to displace supports use a Cnode and displace the Cnode) is not the same as displacing the pipe downward 1 inch. In the first case the pipe could still lift off the support and in the second case it cannot move in the vertical, but is fixed with a negative 1-inch displacement.
