No, the alphabet was secret knowledge belonging only to the initiated priest class before people stole it and divulged it to the public. Now you owe their descendants royalties for a lifetime use of the alphabet, unless you're a thief.

Well, anyone can create an alphabet. You just take a font and change one character.

So anything you do can and will be stolen. There's no reason for you to make anything. Thank you for reinforcing my point.
