Tl;dw Default config is 16gb ram, 256gb ssd
32gb ram is 450$ upgrade, 2tb ssd is 800$ Amazon prices are 120-150$ for 64gb ram or 2tb nvme ssd

So maxing out both costs 1250 for a ~300$ (retail) upgrade, if that were possible.

but only as in the modifications to Falcon 9 to make Falcon Heavy, right?

surprisingly not most of the time I checked.

Laptop/Mobile x86 seemed rather competetive to Laptop/Mobile ARM in performance/Watt
