What do you have in mind as far as the noise goes? I know that even monitoring signal through the MCI in input mode (no tape) that there is an increased noise level. So you're going to be getting a combination of both tape noise and electronics noise, obviously.
I may be able to generate those files for you this weekend.
Speaking of noise. I've realized that I really like hearing that tape hiss during the "silence" between notes. When I hear digital black in comparison, it sounds weird. There was actually a part in my band's record where during a break sounds faded into silence. It sounded so odd to me that I decided to paste in some background noise from our organ. Ahh...much better.
