To my knowledge no suction-type American reed organs have been sampled for Hauptwerk. Maybe one day in the distant future when I am able to find the time to learn how to create sample sets I may attempt to sample one of my own (I have several Estey instruments of various sizes and a big one by the Canadian firm of Dominion, all thoroughly restored and tuned) but that's a very long way off.
However there have been some early efforts at reed organ sampling for Hauptwerk using pressure-style French instruments. Paul Delfierre has produced a few sample sets.

These sample sets date back a few years now and the website appears not to have been updated for more than three years.
The inevitable comparison will be made between the quality of these early sample sets and the high standards of today (such as noticeable glitches in the repeat point of the occasional loop) but they represent a small but significant keyboard genre. In addition to the traditional French style instruments by Debain his website mentions a small single-rank Mannborg suction instrument, but I couldn't say if they are still available today.
If a reed organ is to be sampled I don't see a problem in relation to noise if the instrument has been properly restored. However I do see a potential issue with the creation of loops due to the inherent nature of reed pitch to fluctuate ever so slightly with changes in wind pressure (suction) being generated by the foot-operated bellows. When tuning a reed organ I always connect up a temporary tell-tale to ensure that each note is tuned with the bellows at exactly the same pressure, and I would imagine that a similar approach would be needed if sampling so that the pitch of each note remains constant throughout the entire loop. The fluctuations are only slight, but they are noticeable when tuning and I think would also be apparent in sampling. I imagine that the job of sampling a reed organ would present its own unique challenges.
