End seed cracking on server without end pillars.

[Jeggor]

I want to crack End seed on a public server. As far as i know, i need both end pillars data and end city/end gateway data for cracker to find seed. But on a target server End was partially regenerated with different seed, so the main island and pillars were genereted using an old seed, and rest is generated by with a new seed.
Is there any way to crack seed using only End Cities or End Gateways?
