Yes I guess the critical point is the blade and disk mount. A plate crown would be good way to use fatter blades.

Btw I thought that the idea behind tapered & raked forks was to give some amount of shock absorption. A properly designed disk fork might not have much compliance left and will gain some weight? (along with the disk hardware). Even if it's simply a long Willits mount. Something to weight against the good performance of (hydraulic?) disk brakes.
