Transfering to another server

Hey guys,

i have some questions about server transfering and the consequences that happen after that. I want to go from EUNE to EUW and it says that if the summoner name on EUW is already taken i will be forced to change it. My first question is if i can force that summoner name change by making a new account and name it exactly like mine on EUNE server. Second question i have is about ranked awards. I'm currently placed platinum IV with bad mmr, if i remember correctly you get to play 1 game and after that it places you to rank close to your MMR. So if my MMR in PLAT IV is really bad, i might be blaced in gold so that means i wont get the platinum rewards ?

Thanks for answering my question.
