I had an account that had 11k roughly and was in a niche that I have forgotten completely, but attempting to transition to a personal account completely failed. The engagement dropped off significantly, and so do the accounts followers. Atleast from my previous experience it is not worth doing what so ever and it leads to having/creating a dead account. If you want more popularity on your personal account I recommend posting regularly, doing SFS, using hashtags properly and promoting yourself on your niche accounts if possible. The child account method also works quite well for personal accounts, so does making fake fan-accounts and asking aesthetic accounts or fashion accounts, etc to repost pictures of you.
