In the 16th century, Polish-Lithuanian nobles started to develop a highly peculiar way of speaking due to a large amount of fluent and skilled Latin speakers, Latin being widely used as a lingua franca. This was on one hand due to the fact that Polish nobility had always looked up to ancient Rome, and on the other to the fantastic but widespread belief stemming from Roman sources that Polish nobles were descendants of the Sarmatians, an Iranian tribe of the 5th century AD. As a result, knowing Latin was considered an important part of 'Sarmatian' culture. It was also indispensable in the public life of the Commonwealth, with many of the political speeches performed in Latin.
This led to an unexpected slang being born through what is known as 'makaronizowanie' (macaronizing): a mixture of Polish and Latin, with Latin heavily influencing Polish sentence structure and word order. This 'macaronic' language was spoken in political gatherings, tribunals, but also in schools and royal courts. The Latin influence on Polish proved very strong – and it took a lot of effort on the part of the linguistic purists of the Enlightenment to 'rectify' it. Polish today still stands out among other Slavic languages as the one with largest amount of Latin loan-words.
So, you challenge is to keep the PLC speaking Macaronic instead of adopting 'real' Polish. I'm not sure how exactly you'd stop those Enlightenment era proto-nationalists from purifying the language or the Enlightenment era leaders from wanting to speaking their 'true language' but I'm sure it can be done.
