Service to recalculate endpoint to execute with endpoint routing

Is there a way to cause endpoint routing to re-calculate the endpoint that is to be executed? Perhaps as a service in DI?

My Scenario: I have a middleware that is often registered after UseRouting. During request processing I have the need to re-write the request so it changes the request path (e.g. from /foo to /bar), but once the next middleware is executed which eventually ends up at UseEndpoints we get a 404 due to the now mismatched path.

I’d love a service in DI to help with this that I can trigger from my middleware.

if("/my/original/path"){
  var endpoint = context.GetEndpoint();
  if(endpoint == null){
    // Execute default response logic
  }else{
    if(endpoint.Metadata.OfType<MyMetadata>().Any())
    {
      // let the endpoint override an execute
    }else
    {
      throw InvalidOperationException("Overriden by mistake.");
    }
  }
}
