[Feature Request] Configurable Emoji / PR Comment templates

It's been years that I've been a fan and contributor to DangerJS, but one thing that always gives me a heart attack is the emoji in the DangerJS signature line -- because it sometimes renders in a clipped way in email Previews:
*note: that this sometimes gets shortened even more awkwardly*

Is there any way to customize this emoji?

A. Would we object to a global change of it to something more neutral or less negatively interpreted?
B. Would we object to a feature allowing people to override what it will be?

I haven't explored the code to see how hard this would be yet, as I first wanted input before submitting a PR.

Thanks for your thoughts!
