This feature used to be in some of the preview builds but Microsoft pulled it out, citing issues with Start screen layouts. They said it would be quite some time before it was put back in, and given the current rate of development I wouldn't expect to see it any time soon, if ever.
For now, even on the latest release build (10.0.14393.693), it is not possible to have a large tile.
Try searching for such an feedback in the Feedback Hub about having a large tile option and upvote it your create our new one. Hopefully, this feature might roll out in the next OS updates, so be ready to install them.
Hope this helps. If it did, give me ...
