When PGP generates keys doesn't it always pick d and e to have
the same number of bits, ie 446 for the strongest type?

Is this the same thing? 

I suppose that if you are allowed leading 0s it isn't a problem
at all, but if the first couple of bits were ones in each key, (a
16:1 chance) wouldn't that significantly reduce the power
required to factor the PK using this approach?

Just a thought,
