I am also working on updating some of the Picker mods (though it seems many others are doing the same, so not sure if I will continue work on these). I have semi-functional versions of Picker Atheneum, Picker Extended, and Picker Dollies available here (google drive link). They're not quite working perfectly just yet, hence why I have not uploaded them to the mod portal.
There are probably better versions of Picker Dollies in this related thread, mine doesn't allow oblong entity rotation (like pumps and combinators in more than two directions) and uninentionally allows movement of entities with multiple cable connections to be pushed much further than they should be.
Picker Dollies and Picker Extended also cause an error when attempting to open the Editor Extensions creative mode testing map, but they still work on any normal map, with all other functionality (that I've tested) intact.
