Bug#1052058: apt: refuses to downgrade itself to a version that works on the system
Apologies. It seems that usrmerge had not successfully performed the merge (another issue). It was installed, as can be seen in my first message, but running /usr/lib/usrmerge/convert-usrmerge manually did the trick. It also merges /lib*.
Thank you and with my best regards,
