It seems to me an ingenious way of guessing a word when it is missing in
the dictionaries. The system you propose seems robust and, if it is used
for a few prefixes that typically have equivalents in the nearby/target
languages, I do not see, a priori, much problem, especially for "long"
prefixes like "anti" or "post" (more problematic would be "re"). Also "LR"
and "RL" can be used if, for example", "post" is not problematic in Catalan
but "pos" is found be to so in Spanish. The system is obviously
overgenerating many words in monolingual dictionaries, but if someone does
not want to use the system you propose for a particular language pair it is
enough not to put the paradigm in the bilingual dictionary, or put it for
fewer prefixes. It has to be well tested, of course.
Anyway, it would probably be safer to differentiate between prefixes for
adjectives, names and verbs for minimizing unwanted overgenerations.
