MY05 Liberty GT DMF to SMF Conversion

So the clutch has decided to let go in my MY05 Liberty GT and I've decided to go down the SMF route as of course its cheaper and I'm not a huge fan of the clutch in Liberty coming from a GC8 WRX.
Now after some research it seems the clutch used if going to a SMF is the same as a GGA & GDB WRX. Does this mean I can get a second hand flywheel from a wreckers from a WRX and just get it machined to suit?
Also is it worth going down the route of getting a Heavy Duty Exedy clutch as I will be using the car to tow my Jetski during summer and don't want to overheat a standard clutch?
So for my showing list contains a Second hand GGA WRX Flywheel and Exedy FJK-7853HD Clutch Kit.
If anyone can verify this is all I need it would greatly be appreciated.
