Some somewhat delayed notes for that a badly made dinner is starting to slowly murder me this evening (there may be no more replies till tomorrow really);
Callie: potentially viable just fine
Erich: Did you want to be some kind of merchant prince who is also an envoy to Taldor you mean? Also possible and all, just thought they were separate ideas. In which case we'll need to eyeball the society of whatever nation you were thinking to be from to tailor you accordingly. Katapesh for instance while technically ruled by an oligarchy in an loose sense, is otherwise entirely trade dominated.
Ruby: Are you looking to be, like, the head of the entire Calistrian church in Oppara? Of some kind of branch of it?
Muse and Ebb: playing each other's cohorts is fine /within reason/. Which is to say, if people use cohorts to get around the no LA characters thing for play options, the GM will cry and also say no and then cry again. Not that I really feel like anyone would do that, I just want to put out there, don't do that. Otherwise, if you're making a pc race style cohort, same general guidelines restrictions (cohorts will use gestalt, and same stat generation, feat per level)
Shadow: I normally am, yes, give me a bit to see how less like death I feel and some meds I took to kick in though. Which is to say, can otherwise talk it out tomorrow night then worse comes to worse.
And finally, stat generation!
Going to go with what a friend of mine calls epic rolling: 5d6, take 3 highest, reroll 1s, roll 7 times, drop lowest roll, arrange to taste otherwise. If you get below +10 in total stat bonuses, reroll the whole shmear. If it again sucks or is just not to your liking, just use 30 point buy.
"Gah, so generous!" you might say, and this is indeed so, but there are several reasons for that.
1) Look at fiction in various media for a bit, from gaming fiction to Arthuriana. How often do you really see the main sorts with some super bad multiple score equivalent (yes yes, Raistlin, fine, good job smart guy ;p), or look at rpg gaming and a variety of even mid range style npcs that are portrayed as being pretty capable across the board in innate capacity. Now those are you! I always get a bit annoyed if in a game about a genre, you don't ever end up with an option to feel like certain things within it. More to the point, if I want you to feel like you can play a character that is into being more broadly able and not exactly or even especially optimized at all, a shot at a better stat spread tends to make that so.
2) So you might notice a bunch of my answers are "potentially, that is totally fine", because that is super true. The flip side to that though is a to this point unspoken "but potentially not". If something ends up looking really, really broken, either at char gen, or how it ends up working out in play through no fault of anyone, I am pretty likely to go "that needs to be changed/dialed back" or even "that just doesn't work". And in games like PF, a note like that can sting. You by then spent a while pondering out your build most likely, after all. And you know, design is tricky and play can go in all kinds of directions, who knows what will go down in practice, so it might be a thing that comes up. So if that sting comes up, I'm inclined to ease the feel of it by otherwise being generous with the other hand, as it were.
Finally, try to flesh and talk out concepts first before completely diving into character build. Levels might end up varying after all.
