Do you have an alternative in mind? If so, then you might be okay to change it earlier rather than later. However, plenty of words are mispronounced initially and just takes one correction for people to remember. Then, you have a unique branded name that no one else has thought of. But still, I have experience with foreign words and people will learn. Don't be embarrassed. Imagine it's the name you were given at birth... would you change it, or just help people pronounce it right? lol....
Teach me.... how is it supposed to be pronounced? Skoo-ta-kip? Doesn't seem that hard to me.
Edit: watched one of your videos. Have you ever said your name during the broadcast, "Hey it's me, scootakip" or add a voiceover when you show your channel name in your intro. Easy. I like the name.
