If we assume Kenny would be the caretaker, then there is the risk of a massive build up of expectation, inspired by memories of past glories and better days, that could be expected to follow his appointment. NESV might see that as a risk if performances weren't to significantly improve after his appointment. Alternatively, if he was a deemed a success, they might feel bound to keep him on for longer than they would like, so as not to disappoint the supporters. Such a situation might cost them the opportunity to hire a younger, more suitable manager, who might be available at the end of the season.
Personally, I would take the risk and begin the search for a longer-term option, to take place between now and the end of the season - if a suitable candidate isn't currently available, that is. It can't be greater than the risk of keeping on Roy.
