Bilal, my honest advice for you would depend on the following points
Best Case Scenario: If your reporters can cover live events and authentic people can grant their presence on the camera every now and then (like Jane's Defence), your channel would remain legit. In such a case it would make sense to show exclusive material (exclusive photos, videos, interviews, event coverage etc) along with an expert analysis which no other fake news outlet can offer and thus would retain your exclusivity.
Worst Case Scenario: Failing above, there is a high risk that you would be competing with all third degree sources on YouTube (even worst would be with a fake English accent) and your voice might get lost in the sea of fake news. In such a case it would be better to stick what you are doing currently since in the worst case scenario; it might even have a negative toll on your website as well.
Conclusion:
If you want to do it, do it GRAND!, otherwise stick to the already great work you are doing! Just reading the news in a fake English accent with some nice background music doesnt increase the legitimacy of the content any further. Quality content doesn't need any HD video effects or testosterone raising music. Best of luck brother!
PS: This is my way of thinking, i might be completely wrong!
