From my experiance with A.I.'s you would have to have the barrel set back as someone else has already said.
For case life use a tight chamber.
A.I's are usually good for 5%+ or-, more powder, but as we all know that doesn't equate to 5% more speed etc.
As a former racer and hot rodder I would do it just to say I did it.
As you have said, you already have a wildcat.
If you do it, I would be interested to know how it turns out.
Good luck
