I agree that Milies (H155, Custom, Pro, Y2K, etc.) should be reintroduced by Heritage.
It certainly would bring a more unique build concept to the market, and separate Heritage from a crowded field of solid/semi-hollow body guitar designs.
At one time Heritage offered a Custom Millie as part of its bespoke program.
