Not in principle, for two reasons:
First, the previous words were accompanied by fixed songs. The same epigraph is the same song, and the words with the same epigraph just sing songs with different contents in the same tone. There is no such song now, no one can sing it, and you can't make up new songs for your new epigraph. You don't support the creation of new epigrams.
Second, in ancient times, the birth of the new Qupai was accompanied by the birth of the new Qupai, and to spread it, it must be recognized by the world and must be a famous artist. The new epigrams after the Tang Dynasty are all the works of famous poets or poets and musicians who know the rhythm. We don't have this condition now, and you are not a famous artist.
But if you write a "new word" yourself, it's ok. After all, if you play it yourself, it doesn't have to be widely circulated, as long as it is catchy and conforms to the basic rules of even words. But it's better not to call it a word, but a poem. Because words generally have songs, poems also have long and short sentences, and the form is informal.
