With Model W's existence seemingly all due because of Albert, or so ZX: Advent states, I've speculated else where that Albert more or less is taking credit for minor alterations to what ultimately was coming into existence prior his involvement and without his assistance. Though since Albert got his hands on the 'remains', it is basically into his favor. But I'd like to offer an alternative theory.

Back in Zero 4, during the Ragnarok Incident... Weil, bound to a machine body within regenerative armor, fusing himself with the Core of Ragnarok, Laevatein... Was whole new type of entity. The entire station becoming his body, the Core remaining his place of Consciousness, was still bound to typical Being set-up... Only difference is, Weil was the Core, thus the Station itself was the Body.

When Conflicting with Zero forces his hand to the Fusion, it was within a situation that would have proven in Weil's favor, had Zero not attacked and destroyed the Core. The Core exploding with Weil as part of it, it basically destroyed the Humanoid body of Weil. What there was after Fusion anyway. Then the Atmospheric re-entry destroyed nearly every critical part of Ragnarok... Leaving Laevatein more vulnerable to impact. Not to say the atmosphere burning didn't have an effect on the Core, it just didn't take enough to have been reduced to nothing.

This event occurred during the Human portion of Alberts life, at least the early portion. With that speculation, Albert would have had some knowledge within Reploid basis and technology. Locating and obtaining the remains of Weil's Laevatein, Albert would have the medium that would ultimately come to shape the future that is ZX.

However, the Laevatein remains had Weil fused within them. Meaning, Weil's body is gone, however he continued to exist within the remains. If there is any extent for his body ability too fused is unknown. Though for the sake of this theory, it exists. To the point that Laevatein would eventually begin to reform. Forming a Composite body of Weil essentially. So even without Albert, the MegaMan Universe would have seen Weil again... In some form or another...

But because Albert got to the remains first, he was able to study the remains and reconfigure it into what he dubbed as Model W. Which would go on to be re-buried, re-uncovered, and led to the Ciel 6 and Model A... Thus setting the ZX events up.

The ZX series would have been very different had Albert not intervened with Laevatein remains. There may not have been the Ciel 6 (that we would have seen, or in the same fashion), no Grey nor Model A (that we would have known)... Instead, it would have set forth another future... Something similar to Ghost in the Shell. With such a threat as Weil continuing to exist, with no Hero's... Someone (Ciel, Allouette?) would have possibly uncovered the Hero Cyber Elf's again... But would most likely have implanted such into newly crafted bodies. It would have essentially been the Hero's Resurrection, not as a BioMetal...

Ciel did create Copy X, who was nearly identical to X. So the others wouldn't have been far fetched. And taking ZX's adaptation of Allouette, Prairie... She would have shown interest in the same, or would have opted to assist Ciel, her older sister. It would have been a team effort, more or less.
