No, because it confuses different threats and precautions, putting the latter into a context in which they are not effective.
Checking against known and weak password DBs is primarily a password quality measurement applied during password creation. It can be used for the suggested monitoring purpose, if it is considered that it detects password leaks with the considerable time delay that it takes to collect leaked passwords in the wild, that it should be expected to detect password re-use or mass psychology rather than leakage from the monitored source, and that traded leaked password databases are basically leftovers for which the skilled attacker who initially obtained the database has no further use.
Indeed, if you actually detect a data breach of the monitored source, an ad-hoc rotation (among other means) would counter that. Regular password rotation, on the other hand, is not meant to protect against such data breaches but to counter the time decay in confidentiality that affects passwords which are subject to systematic risk of disclosure, i.e. entered manually. These passwords are usually picked up through shoulder surfing or CCTV and never make it into a database release; and in most cases they are never used for malicious purposes, but with confidentiality as a key requirement for a password, you want to re-establish it from time to time.
