Lucie's List needs cover image (and profile image) for exclusive/insiders FB group

Hello - I run a website for new moms called Lucie's List. We are creating a private FB group for "insiders", who are readers and supporters of our site and content. Please see existing (public) FB page: https://www.facebook.com/LuciesList/ We need a cover image and profile image for this FB group, I can do the rest. The visual style should be consistent with the existing brand, I'll attach the guidelines below. The idea is that this audience is a special group of trusted readers and followers, so the cover image and profile image should convey that feeling. I can simply be a variation of our existing banner with modifications.

I just need the cover photo and profile photo
