People could lug their old bodies to the hospital to have their chips scooped out and shoved back in their necks for a flat fee of 1000c. Perhaps to include the vast amount of Medical we have around, you could make this process doable by nurses, just a simple point and jab with a very low skillcheck (I still vote biotech). Ambiently, this would increase the ability for people around Withmore to afford clone remapping - halving the price. PCs could take a gamble, deciding to use some of that remapping chy they saved over time to pay a recovery specialist to nab their body and stick their chip on ice. Enterprising recovery specialists could even negotiate insurance on that front.
Right now remapping is a chyen sink. Chyen sinks are good for the economy, but this one hits newer players harder. Certain jobs get free remapping, so cool, let those guys opt in or out each time they remap of having their chip transferred.
The room for shenanigans grows - what happens if you decide not to get your chip auto installed? Once your chip decays, is stolen, or is incinerated, your former alias is freed up for the taking by enemies, hired hands, or friends. Can't find your body? Oh no! Got to get to a cyberdoc before the SIC puppy rats you out... or don't and hide from the network entirely!
This would take a lot of coding tweaks of course and I know I haven't thought of every consequence something like this would bring, but I thought I'd drop it by. :)
