An aileron roll in a perfect world is 1G, sure, close enough. To achieve this you need a high enough rate of roll and enough momentum. A slow roll however will vary between 1G and -1 G. The point is a 1G aileron roll only happens in a decent aircraft when conducted correctly. Anything not designed for it, or with a slower roll rate, will not produce a constant 1 G roll (unless height is sacrificed) and will easily exceed that if things go awry.
I agree - aerobatics in anything not certified for it is asking for trouble. You might get away with it once or a hundred times, but it will sting you eventually. We had a pilot tried aileron rolls in a PA28 years ago - singificant damage was done to the structure.
