The restriction is the 85. if you have 10 e.e. coming in, you have to get down to 75 prior
This is true, but I don't think it's that easy to manipulate the 85 in the middle of the year. While I'm not sure about this, I think the only way a scholarship can be substituted is if you're using one for at player who graduated no later than the fall semester. The point is that you can't just drop any player during the middle of the year and give his ship to someone else. Between years, yes, but not during. This is why it's difficult to have significant number of EEs if you're not reasonable close on the numbers to begin with. I could be wrong though.
PS I don't mean to imply that comment says anything about how easy or difficult it would be to allow ten.
