As a tower controller I would transmit blind, instruct a colleague to use Aldis lamp (however insignificant that might be!) and also contact approach to get him/her to transmit blind the landing clearance. Would also prep the operations dept to have a "follow me" vehicle on standby to lead aircraft to stand.
If runway not usable, for whatever reason, I would consider turning off the runway & approach lights in order to dissuade pilot from landing...
