fender standard neck

Help with a Fender Start neck Lefty?
My plan is to buy a standard Fender Start Floyd Rose Hopefully I'll get it soon and when I do I want take the neck out and buy a lefty neck on eBay for two reasons 1. The neck has 22 frets 2. I like the head back, looks good would be screwed into a trash can Lefty guitar neck?
If an exact fit and requires no modification, replacement of the output with a new neck does not hurt a bit. Just remember to hold on to the original, if you ever decide to sell the guitar.
