From a performance stand point I don't really thinks it's worth the dollars doing anything like this to a Honda auto. I have no clue why Honda autos are so slow to respond. I test drove an auto before I bought my 6 Speed and I seriously was going to go with a different car. It felt like it had no power at all. I took out a Civic Si and was more happy with that just didn't like the looks and the crampy feel to it.. So I came to the conclusion that Honda just has ****ty autos and ordered a 6 Speed without even driving one. In reality I'd take an auto hands down and throw in a converter and 9 times out of 10 you'll run the manuals every time, and way more consistent, but right off the bat Hondas auto are a full second plus slower then a 6 speed.
