I was curious, so I've built it: 255MB.
27% better, looks interesting :)

OK, then I'm adding it as a subtask of the "phase three" on the
incremental updates roadmap: #6425. (Phases one and two are MUST for
shipping this feature in a Tails release, and shall be completed by
the end of the year. Phase three is for whatever improvement would be
great to add later.) Of course, if anyone finishes this work earlier,
then it can probably go into the first release with incremental
updates :)
Cheers,
