The idea on a hard-top sounds good, "if the price was right", but price is normally dependent on demand. I imagine for classic Morgan owners with Trad hoods its less complex to fit, though I read somewhere that each hard top is bespoke to the car. Ok, it may be a limited niche, but I would also be interested in a Plus 8 hardtop if it were like image below. Who knows, there must be a few Speedster owners out there that have wind-chill exposure and want to come in from the cold.
