Excellent overview, thank you! Two remarks:

-One-, for now it seems that a coordinated evacuation to Egypt is discussed/considered (Egypt can economically not afford a war with Israel at the moment) which probably would lead to a repetition of 1948 and could be final if the same scenario occurs with the West Bank and Jordan after an "uprising". This possibility also largely explains Israel's attacks on UNRWA and the UN in general (to stop/prevent a permanent refugee status for the Palestinians). As an (out of the box) alternative solution I propose evacuation to (UN peace force controlled) refugee camps in Israel (https://www.linkedin.com/posts/johannes-cornelis-van-nieuwkerk-27527a3_israel-will-coordinate-with-egypt-on-palestinian-activity-7164385671275560960-1tR-).

-Two- such relocation could be a starting point for an alternative coexistence solution (regardless of whether this turns out to be a one or a two state one) . For peacebuilding only non-violent interaction matters, so far there was truce and walls, never peacebuilding as equals: www.canaan.community & www.pax.ngo
