Suntour made 34t freewheel cogs back when, so I'd bet at least a sixer that your VG-T Luxe and your Shimano MegaRange will play nice. And Fujis had long RD hangers, or at least my '85 League does. (1980 Superbe clears a 26 with room to spare, and I bert I could get a 28 in there. Spec is 23t max. It shifts better than I do.)
I'd be very surprised if it didn't Just Work (tm).
