No I wouldn't think it'd matter. As long as you're happy with the lifting routine and separating the days accordingly. If you're doing the CN on Friday from now, you could do HIIT that next day if you wanted as well.
Yeah I keep flip flopping my CNs thinking it will be better one night or another but I'm gong back to Fri this week and will keep it there until July when I'll go to Thurs again.I thought Kiefer said in a podcast recently that HIIT is best done 2 days after CN because our muscles are still trying to hold on to the glycogen. I think it was the same podcast where he talked about doing the one long workout (maybe a Q&A podcast or one of the Research ones).
