Perhaps. But when you say, " Roll 1d8 and divide by two, round up, then add modifiers, " the obvious reply is going to be, " Why did you not just tell me to bring my d4 then? " And on the other hand, it is not obvious when you say, " Roll 3d4, " that someone might reasonably complain, " Why did not not just tell me to bring a d12? "
But 3d4 isn't 1-12. In order to get 1-12 from a d4, you'd also need to roll another die that is divisible by 3, like a d6
if the d6 is 1-2, then the d4 would be 1-4. If the d6 is 3-4, the d4 would be 5-8, and if the d6 is 5-6, the d4 roll would be 9-12.
While a d8 can reproduce a d4 exactly with one roll.
