Who'dda thunk it? Back in 1984, before the Classic anime series (but after their appearance in the Crusher Joe feature film), there was a garage kit, #9 in the series produced by Tama Casbah, featuring the Lovely Angels riding a hover platform. The model is about 1/12-scale, making the figures about 6 inches (14 cm.) tall. I don't have an image of the completed model, but it is based on the Yasuhiko Yoshikazu painting shown above (sadly, the kit does not include Mughi...).
Well, here's a more contemporary set: Moonlighter introduced his 1/6-scale Yuri figure at the Summer 2003 Wonder Festival and has since followed up with Kei in Winter(?) of 2004; you can see much more of both of them at his site
