"In 5 years' time I'll have a new wife" vs "In 5 years' time I'll have had a new wife"

"In 5 years' time I'll have a new wife" vs "In 5 years' time I'll have had a new wife"
Do these both sound natural? Does the second one imply that I might not have a new wife anymore in 5 years time? what is the difference and correct use, if im divorced now and saying in 5 years time i will marry again...
