You're going to take the off-hand remark of a man who wanted nothing else than to have the "Prince of Gotham" helping the LoS in destroying the city? They would do ANYTHING to search for him even if he was declared dead years earlier by Mr. Earle. I highly doubt that would be the case of anyone else when Bruce is assumed to be dead at the end of TDKR.
