Can patches be validated?

[Ghirigoro]

Say I have a schema like this:

const Schema = Type.Object({a:Type.Number(), b:Type.String()});

and I have a patch that I want to apply to it:

const patch = {op:"replace", path:"/a", value:"oops"};

Is there a way to validate that if patch is applied it will produce a valid value for Schema?

P.S. - I know that I can apply the patch and then validate the resulting object but if you have a large object with very frequent patches, this can get expensive.
