I am shocked at how many clearly false answers have already been posted stating that this is impossible. It obviously isn't impossible, as it has already been successful many times throughout history.
My favourite such example is Hangul, the alphabet used across Korea since the 15th century. Prior to Hangul Koreans were writing with Chinese symbols, however the Chinese symbols were extremely difficult to learn as a Korean-speaker because they didn't fit the Korean language intuitively at all.
The language-loving YouTuber <PERSON> does a great job of explaining the origins of this language in his YouTube video on the topic, which I don't think I can beat, so I'm going to quote some his commentary explaining how this incredible language came to be:
Not too many people could read and write Korean before Hangul.
Mostly, it was just upper class academics who could read and write, and most of these academics didn't particularly mind all of the <PERSON> insanity, because they wanted to be more like China, which, for them, was a symbol of refinement and civilization.
So, who eventually did come along to propose something different? None other than the king himself, <PERSON>. <PERSON> was king of Korea during the early 1400s, and he was one of Korea's coolest kings, and not just because he personally invented Hangul.
For one thing, he was a hardcore Confucianist. 466
He believed that it was his duty to use his power to benefit the people as best he could, and one of the major things he did was to begin appointing people to government positions based on their merit, without regard to class or wealth.
But one of the biggest confucian principals he believed in was that everyone should seek to improve themselves by studying and learning.
So, not surprisingly, he was rather deeply disturbed by the fact that almost no one in his entire kingdom could read or write, and he didn't blame this on his people either.
He knew how insanely hard the current system was. He himself actually said at one point that trying to use Chinese characters for Korean was "like trying to fit a square handle into a round hole."
Because one of his main goals was to make a system that was really easy to learn, he wound up creating probably the simplest, easiest writing system in the world.
Seriously, if I were trying to teach you this system in this video, I would probably mostly done by now. I'll post a link to a short comic in the description that claims to be able to teach it to you in 15 minutes, but I actually think that that's a bit high. Seriously, just read the comic through and you’ll be able to read and write <PERSON> by the end of it.
Because it was so easy to tell how things were pronounced based on how the symbols looked, this system spread all across Korea like wildfire after <PERSON> invented it.
<PERSON> said of these symbols that "A wise man can acquaint himself with them before the morning is over; a stupid man can learn them in the space of ten days." And he was right. In fact, it was so effective at educating the population, that latter kings tried to abolish it because they thought it was making people too smart.
The Korean writing system, designed purposefully to be easy and fast to learn, was completely successful, as is proved by its continued use today some half-a-millenia later. 805
