If you can double the number of virtual machines by cutting them
into halves: the price of the storage cannot going down that fast
and big enough as that doubling the storage would be cheaper.

If the goal is to massively increase the number of VMs that can be run on the
available storage an alternative approach is to use de-duplication, either
automatic on the host filesystem or block level, or manually with qemu qcow2
base images.

For booting over a metered network connection, it's not the size of the remote
image that matters but how much of it is transferred. As far as I know, python
uses the time of last modification to decide whether to re-compile, i.e. the
contents of the py files are normally not requested. Therefore, to reduce the
network traffic, one needs to minimise how much traffic is wasted on py data
due to block sharing and readahead, e.g. with mksquashfs -sort.
