Looking to develop a mod-mod of Angels

[Mylon]

I'm seeking some input for developing a mod of Angels.

Goal: Add extra metals to Angels to restore some of the Angels-side flavor of Bob + Angels to Vanilla + Angels. With this mod mod, players must perform more advanced steps of angels ore sorting to build medium to late game items instead of relying entirely on crushing + smelting.

By modifying vanilla recipes to include additional or different materials, the Angels refining steps become more interesting and one has to perform the more advanced ore sorting/refining steps to get those materials. I want to keep the number of extra metals to 4 at most (one metal exclusive to each Chrotinnium and Jivolite), with maybe 1-4 alloys.

Changes to refining:
Chrotinnium sorting yields alumina chunks which must be refined into aluminum plates
Jivolite yields gold.
3 ores yield lead in varying amounts.


Vanilla items to use different/more metals:
Battery (lead?)
Flying Robot Frame (Aluminum)
Low Density Structure (Aluminium)
Advanced Circuit (gold wire, solder)
High Tech Science pack (Gold wire)
Solar Panels (Gold?)
Rocket fuel (aluminum)


Just kinda brainstorming here. If anyone wants to chime in and provide more ideas, I'll be happy to consider them.
