Asking some coworkers to drinks?

I’m in a text group chat with two of my female coworkers (I’m a male) where we text about nonsense. We’re all around the same age (late 20s). They each have long-term partners, so I know there’s no romantic possibility.

Would it be weird to ask them if they wanted to get drinks after work sometime? Is that exclusionary to the rest of our coworkers who aren’t in our text group?

Thanks!
