I did a comparison of the po directory from bazaar. The following are included with WUBI but not in Ubiquity:
af.po, as.po, br.po, crh.po, csb.po, various flavours of english (en_AU/CA/GB), fa.po, fy.po, is.po, jv.po, kab.po, kn.po, mo.po, ms.po, mt.po, nb.po, nn.po, te.po, tw.po, ur.po, uz.po, wae.po, zh_HK.po
There are some in Ubiquity that are not in WUBI as well.
Anyway - based on that it would be no small task to get the two in synch.
