Good Luck.... I can tell you your going to have a hell of a time with the front end swap.... a whole bunch more needs to be done vice what needed to be done with the GD....the $$$ figure will be quite a bit more than the conversion for the GD..
Also for some of the J`s parts you had listed the T-Body/ Rollcenter adjusters/ Fender bars work on the North Amereica 09 Fit...

other stuff not to sure of..but....Looking forward to seeing what you guys come up with....
