What are my alternatives or options for "Blog Details" widget?

The widget I am talking about is this one, for example as used here:

 Coming Soon! Boston Verint Community User Group 

This renders reasonably well when you have the layout set with a sidebar:

We have decided that this takes up too much "real estate" and want to prioritise the blog content instead, this lends itself better for mobile layout too, and it's something that 'medium' for example does for blog posts:

It's effectively a 'single column'.

On verint though, this happens:

As this is an 'out of the box' widget, we want to look to have alternatives that are 'out of the box' or ideally for this to be changed from Verint.

So I ask, what are my alternatives or options? This widget does not have any options, only to change the name or title of it when going into its configuration.

Are we resigned to creating a custom widget, or is it likely to have the behaviour of this manipulated in a different way that can easily survive platform upgrades?
