I've wondered about this myself, Nathaniel. One thing is for sure: if you go about it in the way that you proposed, your broker will love you. Long time. ❤️
That being said, the idea is not without merit. It should work well on certain set-ups; for instance, buying at the break of high/low of the day, when you expect a sharp breakout. However, consider this: most trader try to go as tight as possible in stop-loss and as large as possible in share size. Another approach would be to go smaller in share size and allow for a wider stop, resulting in smaller wins but also fewer losses.
