Here's what I think:

Your semblance is not actually set in stone as a child and when your aura is still locked. Instead, your semblance becomes 'substantial' or basically comes 'into existance' at the moment your aura is unlocked.

Your semblance is determined by your personality and what was on your mind (whether conscious or subconcious I haven't really thought about) when the aura was unlocked; it can change a bit when things happen that result in a major personality shift (whether it be a seriously tragic event, or brain damage, or whatever), but it will not change completely. Instead, it will change visually or maybe a little bit of it will tweak (like someone who's semblance is making clones may change in how the clones manifest, ie Blakes clones manifesting as inky-shadows instead of just images, which when dispelled block the opponents view for a second).

Your aura doesn't affect your semblance beyond how many times you can use it, and what it looks like when it manifests (such as Ruby who has red aura, so her rose petals are red, as opposed to Sun who has yellow aura, so his clones were yellow).

Aura and Semblance are technically connected but they are seperate things. Semblance is a direct application of Aura determined by your personality at the time of the unlocking of your Aura, but beyond that they are not connected. Everything about your semblance is determined by your personality/mind. Aura is a direct application of your soul, but is not tied to your mind/personality beyond what colour it manifests as. Anyone can learn Aura, because everyone has a soul, but only you can learn your Semblance, which only actually comes into a solid existence at the time of unlocking your aura based purely on your personality and conscious/subconscious thoughts.

Anythig you want me to explain further about my headcannon?
