No, that wouldn;t work, since you would need to hex the client and then implement all of the new features, and really old hexed clients don't work. I actually tried to get an item hack to work by hexing a 4.0.0 client, but it didn't work.
So I have no idea how to code but I would like to share an idea. Is it possible to take the swf file from rotmg site and make a brand new client. Take coding from the old hacks and make a new one with them. This in my mind might fix lag issues and many errors and would only take a little bit of time. I find most of the hacks are old ones that have a line or two changed. Let me know what you guys think.

Disregard what these idiots above said, what you said is what you're meant to do (oh and you can find a lot of sources in older mod selector releases).
Is it possible? Sure. Would it be worth the time? 100% not.
