I don't think anyone has yet. I know Mxlppxl has been making some attempts, and got up to I believe the green (~2000+ items - which is impressive) tier.
I have a dedicated server (Leighzer Server) with most of my mods where the goal is to beat factoricons, but I am still in bootstrapping/pre space science phase.
I'd like to get a steady 60spm, and get into some infinite research tiers - then start the factoricon build.
I'm thinking bot based is the only practical way. One uranium assembler per recipe, max prodded and surrounded with 12 beacons. Plopping down all the buildings, then going through the worst part of clicking through all the GUI's to set the recipes.
If I get the rocket made I will be sure to upload screenshots!
