Will I get good results using a flush trim router bit on 3mm carbon fiber plate?

I’m trying to cut out some geometry from a 3mm carbon fiber plate. I’ve 3d printed a plastic profile of the part I need. My plan is to attach the plastic part (with clamps, double-sided tape, through holes and bolts?—suggestions welcomed) and then trace the shape with a flush trim bit on my router. I’m just wondering if this will lead to a nice result of if it’s going to mangle the edge of the finished work. Do I need to buy a special kind of flush trim router bit for this operation or would the ordinary one in my basic router bit kit work?

I should add I do plan to wear long sleeves and my N95 mask, and perform the cuts outside. Any additional advice?

Thanks in advance for any suggestions or advice!
