Express - Replace middleware on runtime

I'm using Express and I would like to replace a middleware on runtime (stop running middleware X and start running middleware Y). I found an easy way to do it, but no one here is giving it as an option:

Instead of using the first middleware, xMiddleware:

app.use(xMiddleware);

I'm wrapping it with another middleware, MyMiddlewareWrap:

MyMiddleware = xMiddleware; 

MyMiddlewareWrap = function (req, res, next) 
{
    MyMiddleware(req, res, next)
}

app.use(MyMiddlewareWrap);

Then, when I want to stop running xMiddleware and start running yMiddleware, I'm assigning yMiddleware to MyMiddleware:

MyMiddleware = yMiddleware;

As a result, xMiddleware doesn't run anymore and yMiddleware is running instead. Does anyone see a problem with it? Is it a good solution?
