That sounds reasonable, and yes a way to revive a dead/slain partner after combat has concluded would be allowed, everyone needs to be able to return to full combat capacity after battle in this.

And yeah it may just be like, two parts of the Lumen Sages, but those two parts are incredibly significant, and almost completely define a Lumen Sage, so while it's two things, it's two really big things.

That said, if you want to vary up your options a bit, you can bring those now-removed styles Devastation Protection and Star Extend after you've adapted them into the styles you're keeping, and make techniques.

A big part of defining styles and the way you're going to actually handle your combat is in your techniques, so I'll be waiting on those.
