It might still be. The body bolts are hidden in cabinets intentionally, but exposed locations are available, especially if using crossmembers (rather than the main frame rails, which may be far enough apart that they're entirely under cabinets other than in the doorway).
One challenge is that recessed tie-downs would usually need more thickness - usually twice as much - than is available in the Escape floor. In a quick search I find one which is shallower, but it isn't the nicest thing to have exposed in the trailer interior: Recessed Pan D-Ring M-15P
. Although "light duty", it looks like it would be more than strong enough for the intended purpose. Something like this might be okay if covered by a removable mat while not in motion.
