Everything is possible. It depends on how much time and effort you are willing to put into something. For example, it took a while to get simple things like text hacking done on Diamond & Pearl, today we are able to write our own scripts and even have some decent tools to design new maps etc.
Resources. You'll find more tutorials, tools, assembly code snippets and whatnot for FireRed. It also offers multiple region maps, better graphics (you can change them, but people are lazy you know) and overall, more research for various things has been done over the last couple years.
