Yes, they're having a new magic book coming out next month I believeOther than that, they do have several guidelines for creating spells, perhaps make a limiter for the # of negative modifiers (like expensive/rare components or can only be cast once a year) that can be applied, and the only limiter that can be placed on top of these would be making it a Dark Ritual.
The guidelines could be used to convert them, however they're free form and subject to DM approval so it might be hard to do.
