Well, the Emperor of Mankind is more or less the Prime Being of humanity (not in origin but at least in status and purpose) just like Lawrence is to the Selforge people, and like him too has beeing doing his best for their sake pretty much from his earliest beginnings.

So Lawrence would definitely relate to him, and seeing the terrible situation the Emperor has been locked into for the past 10 millenia (stuck between life and death fighting in the Immaterium to hinder the growing influence of the Chaos God, while watching his life's work degenerate into the crazy religious totalitarism he so dearly aimed to avoid and inexorably apart fall apart by constant external threats and internal corruption without being able to do anything about it), he would probably decide to lend a hand and resurrect the Emperor by cafting a suitable physical vessel and transferring into it his spiritual body currently in the (now purged) Warp, so he may resume his good work and fix the mess his Imperium has become, on the condition of toning down the steamroller imperialism and learning to play reasonably nice with other species.

Considering the untenable status quo he has been dealing with for so long, the Emperor is most likely to accept this very generous offer, especially after witnessing the extermination of the Chaos Gods from a front-row seat, that was one of his primary long-term objectives.
