Carter, i didn´t wanted just to answer: yes we can integrate the quick migrate script.
You can find the script attached. There is also an automatism included to disconnect removable medias. Furthermore only host will be given as a choice that are online and not the vm source host.
And a nice progress bar is there as a gimmick
Dray & Drop would be cool, but I don´t know if people like the native VMware behaviour go away. So it´s difficult to integrate drag & drop with custom scripts without coming up with an additional script menu.
Thanks for your comment and the valuable feedback
