A hui hou kakou you ka aloha pumehana?

This phrase is grammatically correct, but it's a bit unusual in its phrasing. It's like saying "See you later with warm love." It might be more natural to say:

* A hui hou me ke aloha pumehana. This translates to "See you later with warm love."

* A hui hou. Eia ka aloha pumehana. This translates to "See you later. Here is warm love."

The meaning is the same in both cases, but the second option is more common in everyday conversation.
