I would just pop the flash manually. If necessary to get the timing right, you can stop down to lengthen the exposure time.
There are plenty of ways to rig a time delay if you are electronically inclined. Go to the library and check out some electronics textbooks to learn how to construct delay units that will be triggered by the camera. You can make them adjustable or fixed. You can even buy pre-made delay units from a decent electronics store. You just have to get one that it appropriately rated to 1. be activated by the camera, and 2. trigger the actual flash after the delay.
However, I think doing it manually is easier, cheaper, and close enough.
