The lower the RPM, the more efficient the engine and hence better fuel consumption. However, it cannot be used as a comparison as the engine itself would be the main factor in the calculation of fuel consumption and not the gear ratio. Furthermore, there are no aftermarket parts to change gear ratios (too much work to be cost effective) and hence it is seldom a factor in the calculation of FC.

The gear ratio is only effective in calculation if you are comparing 2 cars of the same make, same engine but different gear ratios.

there are plenty of aftermarket 1-5 gear ratio and final drive. They even can custom made for you if your pocket is deep enough.

But you are right, the RPM at certain speed is all affected by the gear ratio and final drive.
