Allowing play on competition course between rounds of club championship strokeplay

While revising our conditions of competition for 2016 the question arose whether or not to permit play on the competition course between the 2 rounds of our senior club championship strokeplay.
Why would we do that, well, it seems that some of the men still have the energy after 18 holes, to play another round (9 or 18holes) and obviously according to the rules they are in breach of 7-1.
The note to this rule allows the committee to permit play and I am interested in your thoughts as to the pro's and con's here.
The older members are not all as competitive as the younger members and it's not clear to us what advantage they would gain at their level of play by playing between rounds. If the pin position changes, it's normally the following morning before the 2nd round.
