Do you live in a place that’s anywhere near a Hindu temple? One benefit of joining a living religion is that you can connect with authentic practitioners, and seek conversion if its right for you.
If you are instead interested in creating your own personal Goddess worship tradition, drawing on British neo-pagan/Wiccan tradition but claiming a Hindu goddess as your own... you could potentially be treading in the territory of appropriation. That is, you might be appropriating some elements of a deity without keeping her in the context of her living worship and culture.
But you are the only one who can examine your actions and make that determination.
