I don't think so because it doesn't make sense from a practical standpoint. They want to spread the Angels out among the segments so they is at least one or two in each segment (for opening/closing, marketing reasons, so they could better highlight each of them, so fans have something to look forward to in each segment, etc) and to give each of them enough time to change into their other outfits. Also, in the Finale they want to highlight the various segment with the Angels. If all the Angels were all in the same segment they wouldn't be able to do that and it doesn't looks as good and impactful visually.
