Mod 0.6 won't handle the strain directly.
But with an additional gearing that takes off the strain from the gears in the Saturn, it could be an option.

In Bullfrog, MOD1 gears are just enough to survive. But those are custom made and wider than normal.

For a new Heavy, we will go for a cascade. Mod 1.5 on the first stage, mod 2 or bigger for the last stage.
Just to cope with wear and tear over the years.
