The FCB1010 is an incredibly flexible pedal. I've owned one for years. There's definitely a way to do what you want natively without a translator. I'd recommend really digging into the FCB1010 manual. The expression pedals can send different MIDI CC #s depending on which footpedal was last pressed.
Could you email me at jbaylies@eventide.com so I can make you a beta tester when emote's scenes is ready?
