Except for a brief period at the beginning, 90 kWh packs are all AWD packs, so you'd have that issue about blocking the front power ports safely. Other than that, I'd think it would fit - Tesla built both types of cars on the same line at the same time for a while, and I can't imagine they'd want to deal with them being different unless there's a good reason for it.

85kWh vs 100kWh: Does it fit?

Ok, understood. I always thought that the BMS was coupled to the battery and that the FW in the cars is generic and just got it's information from the BMS.
So that means that technically the 90kWh would connect to the 85kWh Model S, but then you have the challenge of getting the car to talk to it.
Okay, I'm confused. Upthread @GSP specifically said there were additional ports on the D battery for the front motor.
Can we maybe get a photo comparison to settle this once and for all?
No idea where anyone would get that idea.
Don't have a photo handy, but the D cars simply have a HV cable that runs from the rear junction box to the front motor. In newer cars they did away with the junction box and use what they call a "rapid splitter" directly on the HV connection in the rear of the car to split the HV between the two motors and charger.
There are no HV connections in the front of the pack. Just the coolant connector.
Looks like I do have an OK photo to show this actually. This is a side by side of the P85s original pack (right) and the P85D Ludicrous pack I replaced it with (left) when doing my P85++ modification.
Photo is from the rear, but there is definitely no second connector in the front of the left pack. It would have to be on a top-facing surface, and those are all visible.
Plus it'd make little sense anyway. The pack contactors are in the rear.

WK057 knows better than I, for sure!
I thought I had read about different packs for the D models, with separate connections for the front motor, here at TMC when the D's were first released. Sorry about spreading misinformation.

Well, it's definitely doable one way or another, just doesn't appear to be doable officially. For example, I can put a 90 pack in my modded P85 because it believes it's a P85D now... so any pack should technically work. Could probably rig something similar for S85s.
