Twitch drops and steam purchases

Hello, I’ve been collecting all my twitch drops on my EUC character since that was the only option for me however with the release of EUW servers I would really like to relocate there even if I have to start over since I’m playing with 300 ping on a good day, but I previously made a purchase through steam to buy the deer mount as well as redeemed all my twitch drops to EUC, will I be able to move these Items to the new server?

from what they have said so far, no… once redeemed on a server its stuck there.
