There is a part of me that really likes the fact that some of these droids are actual characters. This way, I can limit what I buy to just that character's parts, get one to keep in a clamshell, get a 2nd to open and I'll be done. With how limited the color combinations are anyway, I'll be hard pressed to find use for Goldie's dome or the dome that is blue/purple with yellow highlights that goes on the gray w/yellow body.
I am slightly tempted to bring some of the 2012/Wave 1 domes with me and see if any of those domes look good on 2015 bodies and vice versa. For example, the white w/yellow R6 dome might look good on the new white w/yellow & gray body, so it will be an interesting challenge for me to see what kind of aesthetically pleasing color combinations I can come up with.
The GH report indicates that the gold parts sell out quick so I guess making a Goldie will probably be the biggest challenge.

Makes sense if you think about it since it is an actual character.
The only thing I can do now is keep my fingers crossed that there are still new parts to be had come mid-June...
