Adaptive layout of 3 elements without duplicating HTML elements. Is it even possible?

Question

How to swap blocks 2 and 3 on a small screen? Without duplicating HTML tags, and the desktop layout of the blocks is not broken. No position absolute.

.wrap {
    display: flex;
}
.col {
    flex-grow: 1;
}
.el {
    flex-grow: 1;
    text-align: center;
    font-size: 50px;
    display: flex;
    align-items: center;
    justify-content: center;
}
.one {
    height: 200px;
    background-color: #8BAFED;
}
.two {
    height: 500px;
    background-color: #FEDDCC;
}
.three {
    height: 400px;
    background-color: #FF7100;
}

@media (max-width: 600px) {
    .wrap {
        flex-direction: column;
    }
}

<div class="wrap">
    <div class="col">
        <div class="el one">1</div>
        <div class="el two">2</div>
    </div>
    <div class="col">
        <div class="el three">3</div>
    </div>
</div>
