Can my boyfriend come to the US to marry me using the visa waiver program if we intend to live in his country after the wedding?

My boyfriend and I would like to marry in Texas. He is a Scotsman while I am a U.S. citizen. Right after our marriage, he would return to the U.K. while I await for my spouse's visa for our intention is to live in the U.K. Therefore, my question is, if he can come to the the U.S. through the Visa Waiver Program without having to apply for the K1 Fiancé Visa? Plus, are there any other unconsidered issues I may not be thinking about such as the marriage license. Thank you for your help.
