A duplicate Spooky Skeleton skin isn't necessary. Save up your points and be patient until you find someone willing to sell it to you or buy it from the Marketplace with F4 in-game. Either that or wait until Halloween
If you happen to find any skins/hats/accessories on the workshop that you would like to see added to Pointshop servers, you can get in touch with
TheXnator.
Thanks for the suggestion.
