If this NFT is generating millions of dollars maybe Elon will consider it, but if the project is new without any assurance that he can get a return of investment well don't expect that he will participate on any of those. Elon Musk is a smart guy so for sure he will prepare to spend his time monitoring his business and other potential investment rather than spending some bucks on NFT collections with no actual value.
Even if the NFT is generating millions of dollars, he wouldn't care because he is not a person who is in need of money so that money can catch his attention. He is a multi-billionaire for god's sake, he doesn't need some money earned from an NFT collection that he will need to spend his time on, he definitely has a lot of work to do other than this.
A person should simply not target him and try to catch his attention with an NFT collection, even if they use his name or something only to gain public interest, they should make it inspired by him but not specifically targeted to him.
