COOP mode and models in SP

[ender00]

Hey guys

I have two questions

1) Is there any coop mod to play a full campaign in JEdi Academy because it is very interesting and I'd like to play it with my father as two jedi knights

2) How to replace player model for example with Darth Maul because I want to play him every mission not writing the cheat all the tame playermodel etc... and I would like to see it in intros of the levels etc.

Greetings
