Even if you didn't have the NULL challenge with Distinct Count, creating a
separate cube for the Distinct Count is a best practice. There are
aggregation and query performance benefits.

The dimensional granularity to the distinct count cube (with the NOT NULL
filter) would be identical to the other cube, so any queries against the
virtual cube would not require any special calculations.
