If one is going to study some Abhidharma for a line into certain Mahayana teachings, then the text would probably be the Vibhasa, not the Kosa. The Vibhasa was around at the time when the main inflow of Mahayana sutras began, and just predates Nagarjuna, too. By the time of Vasubandhu's Kosa, most of the Mahayana sutras had already been compiled. Therefore, it can't be used as a lead in, as that would be anachronistic. Moreover, the Kosa often argues against the Vibhasa, and the Sarvastivadin teachers criticized the Kosa for not representing the school.
Despite this, I still think that the Kosa is an amazing text. But it is as much Sautrantika as it is Vibhasika. If one wishes to get into late Mahayana, especially the Yogacara / Vijnaptimatra system(s), then of course it is an excellent text.
If one finds the Kosa too long, then something like the Abhidharma Avatara, the Sara / Hrdaya, or the like, would be very useful, too.
Though in the end, I would hesitate to put any on a "must have" list for Mahayana study. After all, none of them are Mahayana texts. (Though Vasu's bits at the end on the bodhisattva path are helpful. But why not just read the Prajnaparamita Upadesa?)
