Editing installed com.apple.Boot.plist on iPC OSX86 installer?

[kDawg]

Is it possible to edit the com.apple.Boot.plist on a fresh install of iPC OSX86? It looks as though it lives in iPC>System>Installation>Packages>BaseSystem.pkg

How would I go about injecting my own Boot.plist that has all my EFI strings already rolled into it?
