The polite and courtesy thing to do would be to send a copy of your version or your created variance of the original CoS Baphoment via E-mail to HPNadramia@churchofsatan.com.
Also it is wise to be polite and courtesy in your E-mail asking if your created version is acceptable for your personal use. Though I would think as long as you are not using your created version in a business capacity, or trying to tie said use of your version in a way to undermine the CoS version, I would not think there would be too big of a problem. Though polite private permission from CoS central is also best in regards to these types of issues. After all they may just post your version on the CoS home page along with the other individual Baphoment creations as well. Very interesting version, this looks to have an inspiration of both images of the CoS Baphoment and the Church of the Subgenuise version. Though these are just my personal views afterall, this is what I would do out of courtesy and respect.
