Particularly, since this is the second kit you have made, I would scale way back in the tweaks you are going to do. You really have no idea what you are starting with. I think the first time I made the kit, I would stick much closer to the way it was intended, maybe add extra oak and plan to backsweeten just a little bit. Then, next time maybe try two things out of the box. Who knows, you might like it just fine with less tweaks.
