The answer is NO, it can't be done through DSDT patching. 

You could try replacing ApplePS2Controller with VoodooPS2Controller (ALPS), the version compiled by Bronxteck.

Look at FAQ #5 to customize 4-5 finger gesture. 

I'm not sure if Alps v8 is supported though. Run the command to determine which version of Alps it has

log show | grep ALPS

FAQs from the Alps kexts thread!

Spoiler

 

FAQs:

1- On Sierra, TouchPad settings (clicking, 2 finger scroll,..)  are not saved across reboots?

Use the attached "Touchpad Settings" app as a startup app and it'll load the settings on startup.

Apple changed something in Sierra that broke compatibility with the base PS2 driver. Apple has yet to document the cha ges, and thus RehabMan (PS2 driver dev) hasn't fixed it yet.

 

2- Keyboard function keys are not working or are messed up?

Again, Apple changed something in Sierra without documenting it. No fix yet. 10.12.1 helps!!

 

3- The touchpad doesn't work as well as on Windows?

Unfortunately, the Linux driver for ALPS touchpads is not too good. Can't do anything about that. 

 

4- How to enable/disable edge scrolling?

set vscrolldivisor and/or hscrolldivisor to 13 (enable) or 0 (disable) in the info.plist

 

5- How to customize 3/4-finger gestures?

In system preferences, go to keyboard > shortcuts > double click an action to change its shortcut, perform a swipe and it'll be saved.
