Why didn't Panasonic/Olympus make a 4:3 ratio half-FF?

The original pen-f film was 24x18, why didn't Olympus or indeed Panasonic follow that ethos when designing m43 or their latest FF? It seems an incredible oversight that Panasonic didn't grow their FF system with full interchangeability with the m43 lenses too.

Lenses would have remained the size of aps-c, they would compete with aps-c head on and many people would gravitate to that format due to its huge benefits in size-weight over FF plus with the multi-aspect nature of a 4:3 sensor they could have offered something totally different and unique and adopted a super35 video approach.

To put it into perspective a half FF sensor measures 24x18, I can't believe the fabrication of this is anything more than halving a FF sensor. The image circle is essentially that of the existing aps-c circle, a tiny bit larger in fact.

But look at the benefits;

24x18 = 432mm half of FF!

aspc- = 366

m43 = 226

That's a big area increase over m43 and aps-c and the lenses remain at aps-c size.

A 16:9 ratio option like the new BlackMagic 12k would also fit a slightly larger multi-aspect sensor. The new Blackmagic sensor is a 12k sensor too!

Its a real shame Panasonic didn't follow Blackmagic's lead, their FF offering as nice as it is is still very large, offers very little competition to Canon/Sony/Nikon apart from that very unique 20-60 lens, but least of all zero interchangeability with m43, not in its ethos or compatibility, very sad!
