Yes, technically. You should provide SVG equivalent to https://en.wikipedia.org/static/images/mobile/copyright/wikipedia-wordmark-en.svg (just with Wikipedia in your language), preferably uploaded on Commons. Then you should vote on it among your community members and if it will be community-approved, we can process the change.
Till everything said above will happen, I'm marking this as Stalled, Lowest.
PS: You don't need to assign me to various task. I am subscribed to all tasks in Wikimedia-Site-requests and I will handle some of them :).
