This may be an actual possibility, and a soon one at that. Next year a collection of Insider short stories (link) is releasing which will collect many of the Legends stories from the magazine. If this sells well I can see them carrying on with it and after they finish publishing all of the old Legends stories I see that it is highly likely that a collection of the Canon insider stories might come. When it comes to the foreign Rebels magazine they are much more unknown, however there is a possibility. At the end of December IDW will publish the first issue of the Smuggler’s Run adaptation. This is a comic that was only ever published in a German magazine, much like the Weapon of a Jedi comic adaptation, and the Rebels magazine comics. If this means that IDW now own the rights to all of the magazine comics, I see that it is likely that we will receive eastern releases of all of these. (Especially with them not actually needing to be translated as they were originally written in English)
The first one is out next month, and the second in September. Here are the Amazon links:
