Or, as has been done to the death on here, if these are coupled up to a compliant DMU, then as long as the door mods and other work is done, the toilet can remain open. EMT have 153's, 156's and 158's. It makes complete sense to send the 153's there to add capacity. Couple up a 153 to a 156/158 that has the compliant bog.
