Converting 2017 Sirrus to 1X

I have a 2017 Sirrus Comp Carbon that I'd really like to convert to a 1X setup. After doing some research, the FSA crankset is unique to Specialized, and they do not make a 1X chainring that is compatible with it...at least that they know of, lol. FSA said it would have to be a mountain chainring, and they didn't know if the chainline would be correct. Seems like they could figure that out. Also, the MegaEXO bottom bracket seems to only work with a handful of different FSA cranksets. So, it looks like I would need to either upgrade t o a different FSA crank that works with the BB, and can be set up with a 1X chainring, or get a different crankset and BB, which opens up my options.

Does anyone have advice or recommendations for this conversion?

Thanks!
Pat
