It might reduce it ever so slightly, but yes.. it won't affect much.
I say put a minimum transfer of x amount of days... like 30/40 days or something.
Add a tax to that and you'd be sweet.
Also, adding 30/40 days to transfers would reduce the "rent a win" concept, which I can't stand. We should be trying to win through superior basketball tactical/management decisions, not buying and selling on the TL.
Just my opinions...
