Downloading everything with 0 dependencies first would be better than today but
far from optimal. The algorithm should focus on keeping both the network and the
CPU/HDD at the highest possible utilization rate at all times.
Another way would be an algorithm that considered the total number of bytes that needs
to be downloaded for each package (the DEB itself plus all dependent DEBs) and then start
with the one that has the least total size. This way you can start the installation
as fast as possible.
