Sure, JKhedrup, Konchok Chidu is quite popular in Karma Kagyu.
And Pakshi Ladrup is a Gongter of sorts, from Yongay Mingyur Dorje, who practiced Karma Kagyu methods and revealed terma as well--those termas are upheld by Karma Kagyu institutions as well--Tsedrup Tabshay Kajor, Yongay Dorje Drollo, and Yongay Pema Benzra, as well as the Pakshi Ladrup.
Karma Kagyu also engages with Chogling Tersar quite extensively. There's also Karma Nyingtik, a complete Nyingtik cycle revealed by Karmapa Rangjung Dorje himself. Lots of so-called "Nyingma" practices are propagated in the Karma Kagyu!
I find it useful to consider the difference between Institutional lineages, and Practice Lineages. Kongtrul outlined the 8 Chariots, which are the practice lineages, collections of instructions brought to Tibet (or, in the case of Chod, Shijay, at least partly originating in Tibet)--and in fact these are all combined and presented, in various ways, as the practice instructions of the currently-extant 5 institutional lineages. I say "5," because, happily, the Jonang have made great strides in the last decade in establishing themselves as an institution. In fact,t he Jonang core is the Dorje Naljor of the Kalachakra, but the Shangpa practices are a large part of the institutional curriculum.
I think we can only address the topic of this thread, in fact, if we understand we're talking about "Institutions." But ultimately, I think it's meaningless.
