On a slightly more serious note.
Q1. Did pyramid construction devolve from a highest order prototype (G1) to inferior copies (Dynasty 4) and then the "hills" of later dynasties?
Q2. Did pyramid construction evolve from lesser order prototypes into G1 and then devolve into the G3s and "hills", notwithstanding the speculation that many may have been constructed upon earlier edifices?
We've kicked this around before but, since the advent of fresh thinking, it may be worthwhile to stake a claim once again.
The following is not news to your good self, but remains my position and is based upon two engineering facets : (1) The Casing Stones(2) The Interior Chambers. The reason being that most epochs could simply lay stones one above the other and, also, dig holes in the ground. However, the mastery of masonry in G1, for example, has not been surpassed since its construction.
Pyramid of Kafre
The Pyramid of Khufu does not exhibit the style of casing stones which is found on Bent Pyramid. Pyramid of Kafre does.
Red Pyramid Pyramid of Khufu
The Pyramid of Khufu does exhibit similarities in the internal construction with Red Pyramid. Pyramid of Kafre does not.
Therefore, an anomaly results.
If Bent and Red are forerunners of Khufu which is a forerunner of Kafre, why do we not see a uniform progression in plans and engineering from Bent to Kafre, keeping in mind the supposed funerary context which Egyptologists maintain is the reason for all pyramid construction?
Perhaps, G1 and G2 were constructed contemporaneously. G1 has been referred to as the Temple of Isis. Isis's male counterpart is Osiris. G1 contains a "womb." G2 does not. The two brightest stars in the sky, Sirius and Canopus, could come into play.
Bent and Red may be inferior clones of the twins with an attempt at combining the features of both. Menkaure is really a bit of a mishmash but, originally, may have been symbolic of Eta Carinae, or similar, before a supernova or such, and may also be contemporaneous.
