welcome to the forum
i too would start afresh. dig everything out and get back to soil and stone then assess what you have and what aort of alpines you would like there.
Take a photo and ask for ideas.
You can have little pockets of alpine gems there or some bigger plants. They can be dwarf shrubs, grasses, perennials, etc.. Things to look at all year round
