Dominants have different icons than characters or enhancements...
So no, you cannot. It has to have the same icon as the dominant you removed. Meaning if you remove a good dom, you discard a good dom, and if you remove an evil dom, you discard an evil dom. Only those options.
I understand your question in regards to the wording, but the capture is the first cost, then there is a second cost that is actually referenced in the benefit.
