A eurocentric language is not really feasable because the majority of the planet are speakers of non-IE languages. So a language structure that is based around a psuedo-latin grammar and wordlist isn't going to be easy for a Thai or Japanese or a Mongolian or a Somali to pick up. The structure and vocabulary are not anything like what a non-IE speaker deals with on a daily basis.
Lojban is slightly better, but I don't think that will take off either.
