Converting AoE2 rating into "SC2 leagues"

So, I have a friend who is completely new to this game who is coming from SC2 where he is a pretty decent player (high diamond). His goal is to get to the same level in AoE2, but we are a bit unsure of how to break down the rating in AoE2 into leagues or even if it's possible at all. This is my thoughts of a rough first draft right now, let me hear your thoughts, if you agree, disagree, and why.

<1450 HD/<1000 Voobly = Bronze.

1450-1600HD/1000-1200 Voobly = Silver

1600HD-1750HD/1200-1400 Voobly = Gold

1750-1900HD/1400-1550 Voobly = Platinum

1900-2200HD/1550-1800 Voobly = Diamond (the skill gap between low and high diamond is pretty large in SC2)

2200+HD/1800-2000 Voobly = Master (HD rating starting to lose relevance at higher levels I feel, but I chose to include it)

2000+ Voobly = GM

Any thoughts? Is this pretty accurate or totally missing the mark?

Cheers!
