The Loki in Ultimates 2 explicitly has the power to change time & space, and used this ability to create documents proving that Thor was Norway's supersolider/ more than a little crazy.
I know it's not the same Loki, but it is written by the guy who is writing Civil War (and knows how the unmasking issue will be resolved.) It's worth noting that the Loki who helps Spider-Man may not be the Loki that we're all familiar with, as JMS (writer of "One More Day") as writer of the Thor relaunch has the complete freedom to relaunch Loki any way he sees fit.
As you just noted, Peter's unmasking had a noticable impact on the world, and the course of Civil War. So if Loki somehow undoes that, he has the power to make it so that Peter's marriage never happened. It's not about making people forget that Peter Parker was Spider-Man, but changing reality so that they never found out. And it's reasonable to assume that if Mary Jane never found out that Peter Parker was Spider-Man, he would never have thought of proposing to her the second time.
This may have a noticeable impact on Spider-Man's official continuity, with some retellings (ie- Spider-Man Blue) set in a different reality than the original comics, which one existing the world in which Mary Jane always knew Peter's identity.
