Having had a quick scout round the internet I suspect it will not be long before this happens as there are already a number of churches and Christian organisations in the USA which do have creationism written into their statements of faith. Presumably these organisations only accept people into membership who also hold those beliefs.
Here are some examples and the precise wording they are using:
http://www.grace4u.org/Topical/doct_stmt.htm
http://www.cruxmagazine.tv/what-we-believe.php (possibly UK based)
“We teach that man was directly and immediately created by God in His image and likeness.”
http://www.thebolthousefoundation.org/statement_of_faith.htm
“We affirm our belief that man was created in the image of God; that he sinned and thereby incurred not only physical death but also that spiritual death which is separation from God, and that all human beings are born with a sinful nature and that those who reach moral responsibility become sinners in thought, word, and deed. (By this statement we affirm that man was created by a direct act of God in His image, not from previously existing creatures, and that all of mankind sinned in Adam and Eve, the historical parents of the entire human race.)”
Other variations include:
“Man was directly and immediately created by God on the sixth day of creation, with appearance of age, in His image and likeness. “
Do a quick google search to see for yourself what might be coming to a church near you.:

This is further evidence of a narrowing of evangelical Christianity.
