Ok, the answer is quite obvious, I figured it out ;)

Path="../ClassEmpire//ClassShip"

My mod will be ready soon, however I have only Polish language version for now. And I have doubts if I should publish it: I'm using textures and mods which I didn't make by myself so there is a copyright question.

New planet types:

Acid, Amoniac Gas Giant, Ash, Brown Dwarf, Boerealis,  Chtonian, Crashed, Cristal, Demon, Frozen, Gas Dwarf, Hydrocarbon, Ice, Ice Giant, Iron, Matuzalem, Monsoon, Oort, Pegasid, Silicon, Protoplanet, Red Desert, Rogue, Savanna, Solaris (unique), Sulfur, Super Jupiter, Vulcan (weaker than Lava), Venus-Type, Water, Wetlands (and few more coming soon)

Many of them have bonuses: for example every Sulfur planet gives you 2% bonus to missile strength.

For every faction there is a unique homeworld with unique bonuses.

I combined my mod with Galaxy of Endless Diversity and MultiOverhaul1.0.1.0 with many new anomalies and platet types (Toxic, Radioactive, Paradise, Carbon, Storm, Shattered, Desolate).

Many new technologies and some new anomalies (e.g. New Typew of Lifeforms, Time Cristals, Giant Red Spot, Ultra-short days). Up to 12 players. New shape of galaxy (Disc-4 removed) with over 325 stars; yet it is unbalanced for AI: for "many" constellations AI is stagnated with its technology when you tend to develop applied casimir effect.
