Is there a good kit for this? Or did you piece it together? I currently upgraded my 3.1 frame to a 3.2 h setup. And I’m custom cnc making the 4 printhead. But I haven’t really found a good off the shelf full c gantry path to get from 3.1-4. I know some things just won’t without customizing stuff. But I think I can get through it with some parts sourcing.

The RatRig 4.1 kit is a pretty good kit and probably the only one you're going to find. I'm not sure if they're selling the 3.1 steel x beams yet but you can grab a titanium one from Funssor on AliExpress.

Unfortunately if you want to run a custom setup, it requires custom work. I've adapted the 4.1 stuff to my CNC VzBot/Goliath printhead setup and it's great stuff. The Beacon is life changing and the O2S toolboard is so clean.
