Hi. Override is not required for this. Only CSS is enough.

Here is example

.article-list .article .article-intro-image, 
.article-list .article .article-featured-video, 
.article-list .article .article-featured-audio, 
.article-list .article .article-feature-gallery {
    margin: 0;
}
.article-list .article-body {
    display: contents;
}
.article-list .article {
    display: grid;
    grid-template-columns: .5fr 1fr;
    gap: 0 20px;
}
.article-list .article > a, 
.article-featured-audio, 
.article-featured-video, 
.article-feature-gallery {
    grid-row: 2/6;
}
.article-header {
    grid-row: 1/2;
    grid-column: 1/-1;
}
.readmore {
    grid-row: 5/6;
    justify-self: end;
}
