Q*GARDENERS by Michael Lau x Crazysmiles @ Shanghai Toy Show 2018
And so the "Q*Gardeners" (*not actual name) is "legit" (not what I had suspected otherwise :p), as seen from these display pics from this year's edition of Shanghai Toy Show 2018, and you have until Saturday April 7th - the last day of STS2018 - to scope them out at Booth A29!
The 6-inch (??) tall figurines themselves are displayed on the different "parts" of the enlarged version of said figures, with Q*MAXX on the head of Maxx, Q*TATTOO on the main body/upper torso, and Q*BRIAN on top of the lower-torso.
Still a mystery to me "who" are producing these figures ("Crazysmiles" themselves?) ... but will update further info when they are revealed.
