However, the Legg-Hutter intelligence metric as specified assumes that agents are separated from their environment, and thus does not directly apply to embodied agents. It may be possible to modify the metric to work on embodied agents, but it is not clear how to do so in general, and this seems especially difficult in situations requiring self-modification.

I think my updateless metrics go a long way towards solving this.

Thanks!

That paragraph was not intended to connote that I know of no promising solutions, but rather to build intuition for the fact that the Legg-Hutter metric does not capture a literal ideal. When someone believes that the Legg-Hutter metric is all you need to measure an agent's intelligence, then it's difficult to motivate alternative proposals (such as your own).

That said, I still need to take a bit more effort to understand your updateless metric, and this is something I hope to do in the near future.
