How would I go about switching Skywarp's and Starscream's heads?

I just got the 2 pack with Faux Magnus only really with the alterior motive of switching the seekers' heads like I saw in a thread in this forum. Cuz you know, Skywarp got the good detailing that Screamer should've gotten.
Here I am thinking its gonna be a simple pop n' switch job like a bunch of the other figures, but it looks like I'll have to dismantle the whole nose cone piece.
Any help on how and what tools to use cuz I ain't handy at all?
