I have tried that in Oxygen Not Included. The problem is that magma quickly solidifies when you remove energy. I wonder if they took that into account.
I tried it successfully in a dream, but the fibrillium outlay eventually caused backflow. I assume they're compensating for that one.
I don’t think it would have any effect at human scale
