Thank you for using JustAnswer.
That's problematic to say the least. While if there's a "good faith" intent to do so, if it's to "circumvent the laws" it would be considered void. Here's the law in Wisconsin:
765.04 Marriage abroad to circumvent the laws.
(1) If any person residing and intending to continue to reside in this state who is disabled or prohibited from contracting marriage under the laws of this state goes into another state or country and there contracts a marriage prohibited or declared void under the laws of this state, such marriage shall be void for all purposes in this state with the same effect as though it had been entered into in this state.
(2) Proof that a person contracting a marriage in another jurisdiction was (a) domiciled in this state within 12 months prior to the marriage, and resumed residence in this state within 18 months after the date of departure therefrom, or (b) at all times after departure from this state, and until returning maintained a place of residence within this state, shall be prima facie evidence that at the time such marriage was contracted the person resided and intended to continue to reside in this state.
(3) No marriage shall be contracted in this state by a party residing and intending to continue to reside in another state or jurisdiction, if such marriage would be void if contracted in such other state or jurisdiction and every marriage celebrated in this state in violation of this provision shall be null and void.
So if you reside there currently and will reside there after the marriage, wait 6 months so that it will clearly be valid. Otherwise, the presumption is that it's void, and it would be up to you to prove that it's not void. Now you can certainly have the ceremony, but have the formal signing of a marital license, etc... after 6 months and that will be the effective legal date of your marriage as far as Wisconsin is concerned.
