There isn't much to it, but that's if you have some experience. I added FX50 brakes to my 1st gen and swapped to SS lines without any DIY. But I've also done brake caliper swaps before, just not on an FX. The principles are the same so it's pretty obvious what the steps are.
However, if you've never done brakes before, it can seem intimidating since the consequences of doing it wrong can be catastrophic. I'd put the DIY up if you have time. It may give someone the confidence to do it themselves.
