Look at how the current Object Results are created. Here is the BadRequestObjectResult. Just an extension of the ObjectResult with a value and StatusCode.

https://github.com/aspnet/Mvc/blob/master/src/Microsoft.AspNetCore.Mvc.Core/BadRequestObjectResult.cs

I created a TimeoutExceptionObjectResult just the same way for 408.

/// 

/// An  that when executed will produce a Request Timeout (408) response.
/// 
[DefaultStatusCode(DefaultStatusCode)]
public class TimeoutExceptionObjectResult : ObjectResult
{
    private const int DefaultStatusCode = StatusCodes.Status408RequestTimeout;

    /// 

    /// Creates a new  instance.
    /// 
    /// Contains the errors to be returned to the client.
    public TimeoutExceptionObjectResult(object error)
        : base(error)
    {
        StatusCode = DefaultStatusCode;
    }
}

Client:

if (ex is TimeoutException)
{
    return new TimeoutExceptionObjectResult("The request timed out.");
}
