Genre Surgery (how would someone change one genre into another?)

After listening to all the Funk and Disco I got from Nate Patrin, Nordikskillz, Donut Bitch and Douglas Wolk (thanks, y'all!).... I got to thinkin'
Could someone take a random Funk tune and "disguise" it as a disco tune by

• Replacing the funky/bluesy/grunty male vocal with a sighing/cooing/orgasming female vocal,
  
• adding a huge sweeping bank of synthetic violions,
  
• adding some guy blowing on a police whistle.

Hmmm.
Then I got to thinking, what would it take to turn a stone cold disco tune into a funk tune....or an R&B tune....or a hip-hop shout out...or a death metal symphony...or polka.

So here's a thread where you, the ILM poster, explains in gory detail the "reconstructive surgery" needed to "disguise" a song that is clearly in one genre as something clearly in a different genre.
using a few steps as possible

Example: "Union of the Snake" by Duran Duran might be disguised as prog with a more ostentatious synth playing, adding a few random solos and arpeggios and filligree wherever it'll fit. without changing the melody or lyrics one single jot or iota.
Granted, "Wild Boys" would require more extensive work...

Anyhow, this thread also continues where an old thread Phase Transitions and Boundary Conditions: Where Does One Genre End and Another Begin? left off.

Go to town, ILM, and have fun.
