OP, perhaps you should learn esperanto. It's supposed to be more logical and easy to use than most romance/germanic languages.
In all honesty, I have often wondered about the revision of language, and what "perfect language" (if such a thing is even possible) might be.
At one point, I came to the conclusion that the perfect language (if the purpose of language is to express reality) would be entirely verbless, since as a philosophical determinist, I am, metaphysically speaking, convinced that "action" is illusory since it implies human agency. In purely philosophical terms, an action is indistinguishable from there being a new state of nouns. (Yes, I know I have to use the verb "to be" to even convey that concept, but in this particular Sprachspiel it would be implicit and would not require explicit use).
With basic operators like conditionals and some rudimentary tenses, you could express anything in the most "real" way possible.
Anyway, if you're after a fun natural language that is fairly logical (face it, Esperanto sucks because nobody speaks it), you should go for Turkish. I'm currently learning it and having great fun. It's completely phonetic, there are hardly any irregular verbs (and all infinitives end in a verb-denoting suffix), there's no noun genders (there aren't even gender pronouns such as he, she and it). It's the most reasoned and sensible natural language I've tried to learn.
