Excellent idea. This would yield the default settings dead-on.

Scaling isn't about the final output. The final output is already in the
standard format. Scaling is about shifting the raw sensor values
displayed by the firmware six digits to the left to match the A/D
converter output. This optimization was introduced to lose several ugly
run-time shift operations.
