FBA: This looks crazy. Will it work?

I've decided to try to use the Claire Schaeffer's Custom Couture Collection V8259 pattern. Like most others, I can't find my size in this pattern (14-16), so I have the larger size pattern (18-20-22). My plan is to draft my smaller size based on what I have. Plus, I get to do an FBA for the first time. My high bust is 35" and my full is 40" so this adjustment cannot be avoided
I used Erica B's instructions for doing an FBA on a shoulder princess seam. (Thanks for the instructions, Erica B. Sorry for squatting on your website all evening.)
Here's a photo of the front piece (with button band on the right side). As you can see the original pattern piece is on the left and my drafted pattern is on the right with changes for a smaller size and for FBA.



THIS LOOKS TOTALLY CRAZY. The original has a nearly straight line, but my drafted piece has an enormous open parenthesis.
How will this jacket go together with such a crazy looking front piece?
Should I try to draft this again in a different way?
Or is this ready to try on my practice fabric?
Do I need to modify the side front for FBA?

Thanks for your help!
