I also understood from what Yhwach said to Haschwalt when they prepared to leave before Ichigo showed up, that one if Yhwach's main goals was to draw out the Royal Guard. But they definitely didn't intend to capture anyone then.

Like you said, kill Yamajii, steal Bankais, recruit Aizen and draw out the RG.
