Unfortunately no. Because all entries with the name DFp_ and DFpS_ should be called xcostum_ now. And then still missing single prefabs. Which is not tragic. But you can also delete all DFp_ and DFpS_ and then add the compopack as a list below. But then you have to add all prefabs from the compopack into the Mod > DF Core > Prefab folder. Then you have theoretically all prefabs from DF Falls and a few more.

So pasting that into DK core and with that prefab list should work on 3.4 no?
