Don't you think a rain of debris would cause something like falling damage (don't spelljamming ships have localized gravity?)? Also, the regurgitation can be voluntary:
How about this? Leave it out of Swallow Whole and add
Vomit (Ex): A nay-churr can regurgitate the contents of its gizzard at any time. If the debris enters a gravity field, the objects do falling damage as usual. The nay-churr will always vomit if it attempts to swallow an object too large to be encompassed by its Engulfing Maw (see above).
A nay-churr does voluntarily disgorge the contents of its stomach on occasion: whenever the creature happens to be inside the air envelope of some object that it isn’t capable of swallowing, such as a planet or a large ship (100 tons or more). The result is a rain of debris in the direction of the gravity plane of the planet or ship.
