That could be done if manufacturers went with some "standard battery factor" like on PCs is 3,5" slot and you can put there HDD, SSD, or whatever fits.

Now you could just exchange battery as a module and replace NCA for Solid State in the future like HDD in the computer and car would be driving just fine.

We're at the laserdisc part of the evolution of EVs. It's too early to standardize now, and besides, there are a lot of real performance advantages that can be gained from customizing battery packaging to the vehicle chassis.
