Continuing this thought- if MarkMC's dm-snapshot-merging patch was in the 
kernel, there could be a button in the live session, such that at any point 
_long after_ the installation, the user could _opt_ to 'fold in' their 
live-session modification.  (i.e. hitting the button triggers a 
dm-snapshot-merge of the tmpfs overlay into the install-destination-drive).
