Keep in mind that Liquid, though the younges to ever join the SAS, was 18 when he joined it.

Considering he would be 12 during the events of The Phantom Pain, it doesn't completely rule out that Eli is Lquid, because Eli is definitely not 18.

It does however, still mess with his background, because Liquid, as a child, was placed in the UK, so it raises questionmarks regardless, whether it be in Africa or Afghanistan, cause he shouldn't be at either location during his childhood. But then again, Kojima did mention there might be some retcons.
