Changing instagram niche question

I have an instagram account with almost 15k followers now, niche is love quotes. I was thinking of changing username, name and bio to a different one but still similar to what most of my followers will still want to follow. Does instagram add certain roadblocks when you do things like this? maybe lowering your reach or w/e? If you are planing to reply with "your followers might unfollow because they don't remember following you or w/e" I completely understand this, im just wondering how instagram reacts to it.

As long as you keep getting engagement you should be fine i think doesnt matter what niche you're on
