Girl names for boys?

I am writing a script for a graphic horror novel I wish to make, and I want to toy with the 'Final Girl Trope' by making the main characters...male-exclusive. But I want to use the names of existing characters from classic horror films such as Halloween or The Texas Chain Saw Massacre. I will be using Laurie as a nickname for my "survivor guy," as Laurie was originally a male name. But I'm going to need your opinion on other names I wish to use...

• Sally (Sally Hardesty, The Texas Chain Saw Massacre)

• Nancy (Nancy Thompson, A Nightmare on Elm Street)

• Alice (Alice Hardy, Friday the 13th)

• Sidney (Sidney Prescott, Scream)

• Jess (Jess Bradford, Black Christmas)

I'm sure most of these sound very feminine, and I personally don't have a problem with that, but I'm still curious as to what your opinions are. Could you possibly even...somehow...convert these female names into male-sounding names? Thanks!
