Killing Lothric first

[Monte]

Is it possible (albeit difficult) to kill the Dancer, Dragonslayer Armour, then the Twin Princes first? Or does the door to the princes' room not open (similar to other "final" bosses in the souls series, which need other milestone bosses to be killed first)?
If you can, does he grant any different dialogue?

cant get into the grand archives without beating every other lord of cinder because the key to open the door to the archives doesn't spawn until you've beaten them

Yeah I just got there :|
Kindof annoying tbh, since I was planning to do a mage run where I went and killed the crystal sage to get the crystal spells early on in the playthrough...

Why do you need to kill the Princes first? Their soul doesn't give any unique spells unless you're after Lothric's Holy Sword I'm guessing? Though that sword is pretty poor in faith scaling and it doesn't scale with INT.

No, I just wondered if he would say something different, since you haven't killed the other lords... Also for the challenge of killing the 2nd last boss 4th.
