mmmmm this is a yummy post! thank you!
id only disagree with you one one small point: i think St. Clement of Alexandria actually interpreted the days literally:
Stromata Book 4.25
Whence He commands them not to touch dead bodies, or approach the dead; not that the body was polluted, but that sin and disobedience were incarnate, and embodied, and dead, and therefore abominable. It was only, then, when a father and mother, a son and daughter died, that the priest was allowed to enter, because these were related only by flesh and seed, to whom the priest was indebted for the immediate cause of his entrance into life. And they purify themselves seven days, the period in which Creation was consummated. For on the seventh day the rest is celebrated; and on the eighth he brings a propitiation, as is written in Ezekiel, according to which propitiation the promise is to be received.
5.6
Now the high priest's robe is the symbol of the world of sense. The seven planets are represented by the five stones and the two carbuncles, for Saturn and the Moon. The former is southern, and moist, and earthy, and heavy; the latter aerial, whence she is called by some Artemis, as if Aerotomos (cutting the air); and the air is cloudy. And cooperating as they did in the production of things here below, those that by Divine Providence are set over the planets are rightly represented as placed on the breast and shoulders; and by them was the work of creation, the first week. And the breast is the seat of the heart and soul.
