Hi
its not possible directly as if there is text it will move the image down for more height and width.
You can try this tweak code that may not 100% perfect but very similar what you need.
Add it in custom css in the template
@media screen and (min-width: 992px){
.item-166 .t4b-slide-item.t4b-slide-item:first-child {padding: 305px 0;}}
It will increase first slide image width and height .
