I will never use Launchpad, however I really like Mission Control. I'd love to disable the Launchpad feature and make my F4 key toggle Mission Control instead. F3 does that already, however I'd like to have both keys assigned to that feature.

I ended up with this problem, too, after upgrading from Snow Leopard to Lion. I really needed my F8 key working as a standard function key for my job. I also really didn't want to delete my entire symbolichotkeys plist, though, so I did some digging.
If anyone else is having this issue still, you can edit your com.apple.symbolichotkeys.plist (located in Library/Preferences) with a basic text editor. Once you're in there just do a search for the number 75. Keys 75 and 76 (76 is the slow animation for when you hold down shift) are the ones for F8 activating mission control. You can just delete those two entries and your F8 key will become just another normal F-Key again. F9 will still work for mission control and you won't lose any other hotkey settings either.
As usual, always make a backup of these files when you're messing with them.
Good luck to anyone else with the issue, and thanks to those here who'd already provided some input and answers.
- Go to System Preferences > Keyboard > Keyboard Shortcuts > Launchpad & Dock and set a keyboard shortcut to Lauchpad.app.
- Use BetterTouchTool to set a custom gesture to activate the keystroke you've set before.

Simple answer: Not really.
You can, however, enable the "Use all F1, F2, etc. keys as standard function keys" option in the Keyboard preference pane:
... and then use BetterTouchTool to map F4 to Expose.
By doing this, all functions of your current function keys won't work and you'll have to remap all of them using BTT as you like.
