It's definitely something I'd like to do one day.
I'm taking a bit of a Factorio break right now though so I'm only doing bug fixes until 2.0 comes out. They're making drastic changes to the modding API with the expansion and I am planning on making this compatible, so it will be a good opportunity for small features like this.
The hearth & furnace basically needs to be bundled with the molten metal turrets. It's really hard to manage the recipes and technologies without it. I don't know what I'm going to do with this feature when 2.0 comes out with official molten metals. The turrets would be ideal on Volcanus so I'll want them for my playthrough.
The ceramic pipes should be in a totally separate mod because they have huge external impact for a very tiny feature.
I don't remember why Shall's is incompatible anymore. It might actually be fine these days, it's hard to keep track of it. The main issue is that I don't play with it and it's hard to have will power to support mods I'll never play.
