So you are saying that you should sand a bigger radius on the sharp trailing edge of the heavy aileron? Can you do the whole wing also so the aileron doesn't wind up different than the wing?
I have been thinking about how to tim my ailerons for a while because I go into a steep left turn if I let go of my stick. I have the same problem with an empty left wing tank and a full right tank and with a passenger that weighs more than me so it is nor just a weight problem. I did some observing last week and with just me in the plane my left aileron is down about 1/4" at the trailing edge in level flight. It is not really a big problem because the stick forces are so light that you don't really notice that you are constantly holding right aileron. The most annoying thing about it is that I have a hell of a time holding the plane level with my left knee when I need to flip the sectional. I have come up with a few solutions that I was going to try on my plane. The first one was to loosen the wing attach bolts and retighten them while someone was twisting the wing tip in the correct direction. I realize that this idea sounds rediculous at first, but a quarter inch aileron is probably only equivalent to a fraction of a degree of wing twist. There isn't a lot of slop in the bolt holes, but you can move the wing tip up and down about a quarter inch before the bolts are tightened. That may be just enough slop to get in a tiny bit of wing twist. Anyway, it is easy to do, doesn't cost anything, and worth a shot before I do something else. My other idea was to put on an adjustable aileron trim tab. That would be easy enough to do just like the elevator trim tab. My third idea was to just put in a spring to pull on the aileron cable in the correct direction. I could also make this a cockpit adjustable trim if I wanted. Any comments on these ideas?

If one would want to avoid using a fixed trim tab on a glass airplane the cure would be to reduce the trailing edge radius of the heavy wing aileron . Some RVer will go so far as to blunt the light wing aileron. A good reason not to paint the aileron prior to flying. In my case it would be no problem as one simply pads two boards and squeezes away. It doesn't take much, this is very, very common thing on RV first flights and is cured easily by this method. It's take just a little more time on a KR but it works.
