Unless there's a need to interact (and there rarely is at an all-hands), it would save everyone time to just prerecord it. Any followup questions can be sent via email with reply-to-all (or an internal mailing list).
I couldn't care less about seeing and feeling my ceo, I just want to do my work and get paid with as little pointless interruptions as possible. Though this could be different if I worked for something I really cared about.
How large is the company you work for? In mine, I can't imagine wanting to "feel the leaders I work for and with" - the very idea of working with them feels like jumping 5 steps up and 2 steps sideways in the corporate org chart.
It was different before acquisition, back when the 90% of the company fit on one floor of an office building, and the CEO was someone you passed by regularly, and who contributed actual engineering. But company this kind and size, they don't do "all-hands" and "town squares" videocalls...
