What kind of project? It's just a workprint. I'd prefer it not be used for anything other than reviewing the progress of this project.
That being said, if it isn't anything you'll be releasing publicly, it's not a problem and the easiest way to alter the framerate is to remux it with TS Muxer or MKV Merge or something like that and set the framerate to your desired fps. It won't reencode the video.
