Fire the flash twice during long exposure photos

I think it would be great if the flash can be fired twice: one when the shutter is opened and then just before it closes. If the exposure is long enough (enough for the flash to recharge), we could get some funny effects. for example, in a dark room we could take a picture of the same person in 2 different places and that without using PS or any digital trick.

you can create 2 raw pictures and then use the raw average or raw merge function
