Big long post
Man, I really am out of practice. This sharn consciousness things sounds kind of iffy, though. You're talking about
these guys, right? What did you do, embed a sharn's mind into one of those intelligent warforged components I seem to recall seeing somewhere but can't remember the details of? ...Something that gives you the extraordinary abilities of the embedded mind? It looks like they don't get the abilities of their component minds, though, so I don't know where you'd be getting the saint abilities. (Even if they do, I'm pretty sure you wouldn't be able to maintain saint status when fusing with non-saints, either. Exalted characters are held to a higher standard than paladins, and saints higher still. The rules on that template are very clear that it's way too powerful precisely because you have to jump through so many hoops to keep it from evaporating.)
Also, you can't do a permanent 8th level spell, either, unless its duration is measured in days. At 1 min/level, that would come out to 480k gold, and there's a rule that says non-epic magic items can't have abilities costing more than 200k. The item's total cost can be higher, but only if it's from combining cheaper abilities. (And that's if you just go straight off the table; I'd be thinking really hard about raising the cost from there on the theory that WTF is up with that spell in the first place. But that doesn't usually come up in optimization exercises.) Even if you could do it, that, plus ~120k for your slotless sevenfold veil would take almost your entire budget.
...wait, how do you get an ancestral weapon when you don't have ancestors? One of those crazy-ass things, I guess; god knows there are plenty. I came up with a trick that involves clicking your heels together an infinite number of times in a single round. It's a free action, you can totally do it! (And it's positively disgusting what you can do with it.)
Hey, wait, if you're using Bo9S stuff, can you still call it an optimized fighter taking down a wizard? ... I guess he's still mostly a fighter-type...
