A longer upper arm or shorter lower arm will not really change the camber curve. Just will allow using less shims with a drop spring. With a drop spring the top of tire pulls in quicker as you are deeper into the curve. What you are thinking may be good? IDK? Maybe, if I was in your situation and wanted to still use the aftermarket arms I might pull the uppers and shorten them 1/4"-3/8". When altered from stock it is hard to have everything be just bolt-in.
