IMHO, that wouldn't be what the tournament was advertised as. Players didn't sign up for it expecting such a system, so i don't think it'd be a good idea to implement it now - unless we receive unanimous agreement from the participants.

That being said, i'm still a proponent of a more traditional approach. This kind of system isn't currently being used among arena members, so it won't be properly teaching the relevant skills or knowledge in terms of character creation - or at the very least, it might deliver a skewed perception of how it's done.
