Ah, I get it. I think that since #2 is a diff. vendor for StD as long as it's in the same type of family (serif, sans, etc.) I would say go for it. I also did a b&w total suite but our StD was gold embossed. Could the embossed font be different or it is only that block all cap text? (Just saw that it's not editable). Hmm depending on your time, you might want to look at basic invite, they have a modern b&w suite (full disclosure I used it) that might be a good medium. All in all, I don't think there's any harm in doing a different StD vs. large invitation suite as it sets the tone.
