I think that would still cause a reduction like gears, due to the radius difference.

To OP:
Just use a two-stage gearbox. It's not that much more expensive to buy a two-stage gearbox than to buy a one-stage.
Alternatively, you can make your own gearboxes. It isn't frightfully hard to do given a mill/ xy drill press or CNC or sponsor for cheap. Designing gearboxes is fun too. You just mix and match vex gears to suit your needs.
