Nope, sorry, even if I think it would be possible to do it, I'm busy and not interested.
The old Holiday skin was a gift from the old dev team years ago. It was totally outdated and I thought it was the right time to update and publish it now as gift for the Winamp community. The localized version in my installer was meant as gift for the people, who used my language pack for so many years.
Also not helpful, that I don't like the Bento skin in general.
Ask in Modern skin forum, maybe you find someone, who will do it, or try it yourself.
