Reposting tiktok video?

Is it bad if i repost my tiktok video? Usually get about 1-3k views on a video. And the last 3 videos i've been getting about 500 views. I am thinking of reposting them. Maybe changing the audio. Will tiktok shadow-ban me for doing this? I feel like maybe changing or adding something different to the video to reduce the chances of tiktok penalizing me. What do you guys think? Should i do it? Or not worth it?
