What do you mean Baleen is not compatible with Bootstrap 3+? Version 1.0 of Baleen comes with Bootstrap 3.0, and it is advertised as “Compatible With Bootstrap 3+” on creativemarket.com, where I bought it. Hence, I expect an important interface component such as the main menu to work with 3.0.3 as well. And also not to have to wait a very long time for it. I hope that you will be able to fix this sooner rather than later.
