If we're prognosticating: I question the idea that the marketplace wants LW to replace HW knives. The poll taken at the beginning of this year shows a normally distributed curve of knife weight preference centered around the common 3-4 oz knife, which is what most people want and expect. I'm on the lightweight side of this curve, you're likely on the heavyweight side, but preferences don't indicate LW is replacing HW. In fact, if you move two steps heavier than the norm (the orange bar) you'll see there are more people in that 'extreme heavy' category than there are in two steps lighter (the green bar) in the 'extreme light' category. There's definitely a solid customer base for knives in the 3-5 oz range and even into the 6 oz range...lotta people love their Shamans. (And on the other end, lotta people love their LW Salts and Bugouts.)
In the meantime, have you checked out some of the copper replacement scales available for the Manix? They can make a Manix weigh >8 ounces! That'll keep you from floating into outer space! The good news for you HW fans is that there are usually easy ways to make a screw-construction knife heavier. Us LW fans have more work to lighten a knife; the aftermarket accessories to lighten, like the AWT scales, are rare.
PS: The irony of my screen name 'Bolster' isn't lost...bolsters make a knife heavier...I chose my name 16 years ago, back when I was into heavy bolstered micarta full-linered knives...! My shift to LW occurred when I morphed from a collector to a user. A job change meant that I was carrying a knife in the field for work a lot more.
