Of course it`s your decision but my advice would be to focus one game at the time.
MTTs take lot of time and variance can be huge. Do you think you could have coaching for both at the same time because if someone coaches you, you need to play a lot of that exact game and do analyzing for those hands. So if there is two games and two guys coaching you, you need to do double amount of work and there is lot of work to do even with one main game.
Don`t wanna sound like killjoy or anything but just my two cents.
