These look interesting, I may look and see how they fit

Metals for You is a bit buggy atm so might want to avoid that one for the time being.

I think in the next release (or 2) I will be introducing the first 3 mods

So, if we try to create the most complex modpack, I think very nice to add all mods by https://mods.factorio.com/user/Timeken . I checked it on ATO and it works fine for me.

Another suggestion: https://mods.factorio.com/mod/SE-ores-integration
This mod can clean all planets from billions of ores. Yes, your factory will be bigger, but you don't need to find another spots (like Angel's ores).

Next suggestion is more complex. What do you think about adding Bob's mods? Yeap, it is enormous work to balance all machines, items, utility staff. But it's necessary for more soft stages and a less grindy of all monstrosity of materials. Some work was done on Cractorio pack (K2+BOBs+BZ).

most of bob's is marked as incompatible with SE

I don't talk about "ore" or "mobs", only machines, bots, logistics and energy.

I recently added these mods to the pack and all seems good for now.
