Wipeout type vehicle?

Hi, guys so I have a game that is around 40 percent complete. I would put it in the genre of endless runner except it has set length tracks . The object is to get near misses in order to scare the ■■■■ out of your passenger…Kinda lame I know . Trouble is the straight-line thing is starting to become quite boring . I would like to add a wipeout style of vehicle control .As opposed to what I have now which is simply a roll to left and right… Should I start from scratch or will it be relatively easy to add yaw control and maybe a hover component I can add my ship bp if necessary.Thanks guys
