Not likely unfortunately thanks to Mozilla, which in all its wisdom, dropped embedding support from Gecko. This means it effectively cannot be hosted outside of Firefox/Seamonkey and forks thereof. This is contrasted by WebKit, which is largely UI toolkit agnostic and can be dropped in just about anywhere.
Funny thing, Epiphany (now known as GNOME Web) was originally built around Gecko, but when Mozilla axed embedding, the project had no choice except to switch web engines and so it’s now built around WebKit instead.
