Revan's Robes are not in this game, but you can get a mod to add them. Same goes for the Star Forge Robes. Note that the Revan Robes are the Evil version, Star Forge Robes are the Good version. They are also now only equippable by pure light or pure dark. The robes are no longer as godlike because of the existence of the various Zeison Sha and similar armors, and their inability to be upgraded. Also, between your crystal and other items, the Wisdom bonus usually does nothing (you can't boost a max of 12 above your real stat).

HIGHLY RECOMMENDED mod: Adds smuggler's compartment, cargo containers, and a lab station to the Ebon Hawk (compartment has some nice stuff). This mod works very well, and is very beneficial:

NOTE: You can have multiple mods active at the same time in this game, without fear of overlap. This is because each mod adds or overrides very specific resources within the game, meaning that unless that exact item is tampered with, you will not have any conflict. These two mods are known to work together without problems.
