Just kidding. But about your point 6. I think edos can't really bleed (as you can see when they get harmed). I think the summoning only worked, because kishi forgot about it, or something.

Edit: After thinking about it again, it might be possible that edos can somehow access/draw their blood if it's needed for a technique.

they clearly bleed when cut. and why wouldn't they. they are created by a caster gaining access to there genetic material then using a summoning jutsu to summon there soul to a living host. said living host has blood so said host should still bleed the only difference is the hosts DNA most likely transforms into the edo tensei's dna
