What if you had no slow twitch muscle fibres?

I’ve read that slow twitch muscle fibres are used for every day activities like standing and moving around ect, and this is primarily due to efficiency correct? But like what if spontaneously all those muscle fibres converted to fast twitch? We would adapt by rewriting our neural Motor circuits To just activate less fibres right? Like you would get used to it and be able to do your every day fine motor control activities eventually right?
