I am glad you are listening and attempting to recreate the classical accent. However I am somewhat thrown off by your message in that you use the word acclaimed (in presumably a facetious manner), and place the word properly in quotes. Are you questioning the general historical linguistical validity of the restored classical accent? See Vox Graeca: The Pronunciation of Classical Greek by W.S. Allen, for an in-depth examination of how the experts have recreated the pronunciation.
In any case, I think the pitch accent, if not in fact then in spirit, is not so difficult that it requires you to imitate Swedish or Chinese prosody. In fact, you simply rise the pitch of your voice instead of the volume of it. It is not that difficult once you practice it for a few minutes.
In fact, your mention of Chinese seems bizarre to me, as the Chinese languages' tonal system is utterly different in every possible way from Greek and a simply pitch accent, and whatever accent Greek had.
I advise you to stop imitating Germanic or other Barbaric languages and instead try Daitz's Pronunciation and Reading of Ancient Greek: A Practical Guide to have what I think is the best chance of making a fairly close approximation of the Greek of Pericles and Cleon.
