Hmm, in that case, I think it might be best not for me to help until I completely understand how the RNG works. I've never really gone this far into the mechanics of a game before (though I've read about it in many threads), and I think it best that I'm not involved yet with playing the TAS.
I WILL however help with everything else. Ok so I've been trying to plan out what would work best. As far as routes go, I'm not completely certain. I DO think, however, that you shouldn't go the Lawful route. Why? Because that would make Denim Lawful, and the only good class with L ali. is Sword Master, and I don't think it'll be worth it. Although he can attack twice, he'll also take a lot of damage. Now you can obviously luck manipulate this, but I think the amount of manipulation total considering all the hits he'll take, you won't be done for years!
For males, I think the best basic classes are Berserkers (for N/C ali.) and possibly a Beast Master and either Ninja or Beast Master for L units. However, whips are really rare. Thing is, you won't get your first whip until Chapter 2, so you might end up with several Ninjas. Knights might be a decent choice very early on, but I think Ninjas are better since they can attack twice and have low weight. Just be sure to watch their health.
As far as Wizards go, I don't think you should consider them; period. Spells can take a huge amount of frames, especially when the Wizard levels up and the spells hit a larger area. Not only will you save TONS of frames because of that, but also because you save frames NOT SHOPPING for spells.
For Male Advanced classes, Terror Knights seem to be the best way for C ali., Sword Master for L, and possibly Dragoons for N. I probably wouldn't recommend Dragoons in the first place, but as far as N's go, that's the only good class available to them. Gunner will probably not be considered. Of course, you could only use members of a certain ali. so that you can have everyone be the same class for one alignment, but then comes in the conflict of "variety and enetertainment". You should decide what's best here.
For females, I think Archers are pretty much the only way to go. Valkyrie is a decent class, but as the Archer levels up, I'm sure they'll do tons more damage than Valkyries. Also, I think Archer is a good class because since they can attack from a distance, as long as the enemy stays in distance, the Archer won't have to move, therefore lessening their WT. That might be something to consider.
As far as miscellaneous classes go, I think Lizard Men are solid fighters who can deal and take a good amount of damage, and Hawk Men for their ability to fly and work well with nearly any type of weapon. That is, of course, if you decide to recruit any. It would be quicker to buy them at shops, but depending on how you play, it may just be a waste of time.
I hope this helps!
