Are there any 7w6 or 7w8 INFJs out there?

I was wondering to all those INFJs out there: What would a 7w8 INFJ look like? Is it more rare for them to be like that similar to how it's rare for ENTPs to be a 1 (1 is basically directly against a healthy ENTPs nature)?

If you've ever met one, are one, or have some thoughts or theories on what they'd be like, I'd love to hear them because I'm genuinely curious.

I'd imagine it'd create a lot of confusion and mistyping to any of those who are.
