King Siegfried in Metalfoe Yangzings?

So I need 3 dark contract and 1 copernicus and 1 lamia to add to my metalfoe yz deck and i have to buy the structure deck in the process, i wanna make use of king siegfried is that possible? The D/D non tuner would be level 4 copernicus and all i would need is a level 4 tuner but i dont want to use denglong because i would rather use him to dump chiwen. Any shenanigans possible to make it a thing? I could easily revive the copernicus with a baxia, or even pendulum summon him but for the rest I need your help. Pend summoning him with Zefraxi+Suanni would be great, zefraxi would turn suanni into a tuner and i could then synchro summon suanni+copernicus into a 3300att siegfried and leave zefraxi as a nine pillar target.
