|I actually suggested that very thing in a post a few days ago - I suggested a Mig variant.|
I should note that much of the cloaking stuff is in Star Wars is Legends...non-canon, but potentially pulled from when they need new ideas (some Legends stuff is semi-canon, like the Knights of the Old Republic game being the inspiration for the Hammerhead corvettes in Star Wars: Rebels and Rogue One isn't EXPLICITLY cannon, but the corvettes are said to be "inspired by an ancient ship design", which kind of makes it semi-canon that they existed.)
I believe the rumors of the Emperor's personal shuttle having a cloak is also Legends (hence: Mig variant).
There is a canon cloaking device, an experimental cloaking ship from Clone Wars, the CGI series (which is canon, as is Rebels)...hm, just read this page:
...apparently, there's more canon sources for cloaking devices now. From the comics (which I haven't read) and the books (only some of which I've read), Darth Maul's ship had a cloaking device, and Tarkin used a corvette using a derivation of the cloaking tech on the Clone Wars era Stealth Ship...
Basically, it's an uncommon/specialized tech. But then, so are hyperdriving Millennium Falcons and Slave 1s, so...
