I have done that a few times, keep in mind with your trench that the enemy can take take cover in your abandoned positions so don't let them or fall well back under cover of smoke. Good place for an arty gold spot if you think you will have to fall back.

Taking over enemy foxholes is a handy tactic sometimes when assaulting.
