It wouldn't be difficult to build. You'd need a common turn signal beeper and a 12V Bluetooth transmitter. Using a line level converter to convert the beeper's speaker-level output to line-level output (with variable gain pots so you could somewhat adjust the beeper output), you'd connect the beeper to the BT and then pair the BT to your Sena. The tricky part would be pairing the BT to your Sena -- you may have to forego another input source like your GPS (assuming you listen to your GPS in your helmet) in order to pair to the beeper.
Would I buy one? Nope. I've trained myself to cancel my signals after every use, even on my bikes with auto-cancellation, and also periodically poke the cancel button even when they're not on.
