I, too, had attempted this, back in the late 80s. The problem was, while most of the early Adventures (also Amber Zones and Double Adventures) were set in the Spinward Marches, a few (and subsequent) adventures were set in the Solomani Rim, and a couple of adventure settings were unspecified. I think some later ones were even located in District 268. The difficulty being, if one strictly followed the canon timeline, some of the events would be occurring simultaneously. Short of an Ancient artifact (gate?) allowing l-o-n-g distance teleportation, it would be all but impossible to campaign through them all sequentially.
It might be possible (fun, even) for a referee to conduct parallel campaigns, with the same players but different character groups adventuring in the different venues.
