i've got an older BMC Alpenchallenge ac01 that i built up from the frame. mine has a steel fork with midfork rack bolts, a proper touring drivetrain and can handle 2" tires.

unfortunately, your stock ac02 is not suitable for loaded touring. sure, you "could" tour on it, but.....
you have a max 37mm tire clearance, 32-spoke wheels, and your 34:32 low gear is 29".
