The art in question is https://www.instagram.com/p/CIfsO2ZD7Rj/ . I Think the concept artist, Jean Giraud, is dead.
While better fitted to our friends at law.SE, the general gist is: No.
Art is protected by copyright, and any adaption (derivative work) requires the OK from the right holders per se. Only 70-75 years after the death of the author (or publication for company works), a work enters the public domain and the copyright expires.
There are some exceptions (fair use/fair dealing/...), but media transformation is not one of them.
Giraud died in 2012, his estate or heirs - or whoever he/they sold the commercial rights to - own the right to ok derivative Works till around 2087.
This is something that might have a precedent, where the line is blurry, someone might have already tried, and in that case the judge's decision in that court case is the official interpretation of the law towards that specific scenario.
There might also be definitive laws regarding "derived works"...
Like the others, I would ask the Law SE for help.
