That's a really interesting design. Likely short-lived due to heat as Nick states, but still interesting.
My solution (not implemented yet; just tested) was to fake the timing so that the hyperflash could not get to the bulb.
You would still get errors on the DIC, though.
The biggest problem for a PnP solution is that the connectors used are customized by GM, so you can't get them at a reasonable price. IIRC, list is ~$90 for a front, turn signal plug/pigtail.
