The potential problem with doing that, especially in EZY's case it that it's fine for leisure pax but are business pax going to be that interested in a mid afternoon flight from LTN when there is so many other options on London - Rome?
If you look at how FR operate from STN they fly a lot of their inbound aircraft from other major cities over Europe into STN first thing in the morning as the STN based aircraft start going out so it attracts business pax.
EZY might struggle to do that at LTN because W6 literally invade LTN at that time. Unless EZY do it with the more leisure based routes, but they don't have bases in ALC, FAO, PMI etc.
