So I ended up buying a VR10 and the tweeter itself does indeed look the same, but the housing it's in is smaller.
VR12 tweeter on the left, VR10 tweeter on the right. Dammit, don't know why Photobucket rotated the picutre. VR12 tweeter is on the top VR10 on the bottom.
Backs of tweeters, again VR12 on the left, VR10 on the right.
I'm going to try calling some local stereo repair shops and see if someone can swap the VR10 tweeter into the VR12 housing. Anyone know if this is possible?
