As a bit of an update, I am running 10.7 under El Capitan with no noticable issues at this point. Some additional steps to what has been done before:
1. Boot to your recovery volume. (Hold CMD-R right after startup chime.)
2. Under the Utilities Menu, select Terminal.
3. Enter "csrutil disable".
4. Go to your hard drive through Terminal. "mv" "CoreFP.framework/" to something else (CoreFP1.framework).
("cd /Volumes/[your hard drive's name]/System/Library/PrivateFrameworks" "mv CoreFP.framework/ CoreFP1.framework")
5. Reboot. Follow remaining steps from previous method.
6. Boot to your recovery volume. Open Terminal.
7. Enter "csrutil enable".
8. Select Restart from the Apple Menu.
