Anyone got any thoughts about the viability of splitting attributes between int and mind?

I really want to be able to use both scholar AND summoner so that I can switch between DPS or healer role depending on the needs of my friends and company-mates, as well as to give myself extra flexibility in the field. But you have the attribute straight-jacket, that summoner needs int and scholar mind, if I split the attributes would it be a serious detriment to progression play?
