可以在IHttpModule上实现.NET事件吗?

这有道理吗?
有没有我没看到的潜在陷阱?

public class ResponseTweaker : IHttpModule {

    // to be a list of subscribers 
    List<Func<HttpApplication, bool>> listRespondants = new List<Func<HttpApplication, bool>>();

    // event that stores its subscribers in a collection
    public event Func<HttpApplication, bool> RequestConfirmation {
        add {
            listRespondants.Add(value);
        }
        remove {
            listRespondants.Remove(value);
        }
    }

    public void Init(HttpApplication context) {
        if (OnGetAnswer(context)) // poll subscribers ...
            // Conditionally Run Module logic to tweak Response ... 
    }

    /* Method that polls subscribers and returns 'true'
     *  if only one of them answers yes.
     */
    bool OnGetAnswer(HttpApplication app) {
        foreach (var respondant in listRespondants)
            if (respondant(app))
                return true;
        return false;
    }

    // etc...
}
