No, sorry. To be honest, a big part of that decision is to protect the visual style of the dashboard. If a dashboard starts getting filled up with a bunch of different website snippets, it becomes a messy and ugly patchwork. I really think a dashboard in your home should have a nice, clean, professional, and unified look. For example, that weather snippet you put on your current dashboard is exactly what I meant. It completely clashes with the rest of the design. It has a blue gradient background with square corners, while all the other elements have a grey background with rounded corners. It has a different font, different typography, different colors… 
As a designer, this is also a personal annoyance of mine with the native Homey dashboard app. Everyone creates nice-looking specialised widgets for it, but every single widget has its own style. While that particular widget may look great on its own, when you combine it with others, it just becomes a big patchwork quilt. And yes, I do understand that this conflicts a bit with the idea that users should be able to do whatever they want. But it’s my app 
, and while it is still in development, I try to facilitate (uniform) solutions to problems like these that actually match the theme of the whole dashboard.
Anyway, I think it is perfectly doable to create a nice weather “widget” with the exact same data using a Homey script and a text widget. I shall make an example tutorial for you on how to create something like that without butchering the style.
