Why?
If you want a good set of people I have always used AzelxTiltyu SylviaxClaude FuryxLevin that's the best way to get a amazing Sety, a double minor blood Arthur & a Valkyrie using Corple. If you want an amazing Faval pair BridgetxJamka, IraxHolyn is good but useless if you don't use the Balmung (iron lance) glitch so IraxLex is still awesome.
I don't care about Sety.
@Ninji: I don't need the Hero Sword. I'm planning on giving Lex Holyn's Silver Sword before the end of Ch5 and Lakche gets the Thunder Sword and the Steel Blade, among other things.
In that case what you got sounds like a good 2nd gen list of child inheritance.
