We have to work out the fact that badges such as those proposed here do not scale accordingly to sites traffic before creating new ones.
The traffic varies highly from one site to another. Unless there are different requirements for badges on all the different sites, maybe according to their registered population, we can't have a badge that would work out well on all sites, being either too hard or too easy to obtain on most sites.
For example, the numbers in op's question would fit well on stack overflow, even though I feel the gold and silver badge are too low (many, many people would gain the silver badge right on badge implementation).
However on music.stackexchange, they are skyhigh, almost impossible to get on such a small traffic site. The higest reputation user there would not even get the silver one.
Wrap-up: No, no new badges unless they have adaptive numbers, and I think we should wait to see how things go out with the new stat before doing this.
That being said, Monica point's out that we have other badges that present this problem. I'd still favor not adding new badges to the lot and waiting for a solution before creating new badges.
