Widespread induced religious conversion on the EU level (send in one colony unit and convert a whole province) is a very poor model. After all, this lets England eliminate Roman Catholicism from Ireland for peanuts and in a space of six months, something that never happened, no matter what the "official" Church of Ireland might have been. Centuries of vicious oppression were unable to compel and enforce this change.
Likewise, with only one exeption (some Polish provinces), the Unia after Florence (1439) was extremely short-lived and ended up merely producing resented minority Uniates in otherwise Orthodox regions.
Generally, from my reading of history, if there was a "state" as Europe would recognize one at the time in place, mass conversion of entire regions simply didn't happen except as part of a general socio-political upheaval (The Reformations, conquest of the Aztecs, the Turkokratia), and in the case of the Turkokratia, it was not really completed in Turkish lands until the ethnic cleansing perpetrated by Turkey in the 1920s upon its Armenian and Greek citizens.
Likewise, in EU currently, the colony of Maryland could NEVER HAVE BEEN ESTABLISHED. Reality contradicts this, of course. Maryland *WAS* established as a haven for British Roman Catholics and it was dones so *after* the UK had abandoned Rome.
