I like the spirit, but you are only looking at it from the refugee perspective.

The amount of hurdles & risks the employer takes is pretty high (e.g. taxes, ID verification, risk of the refugee getting their claim denied, etc).

Seems your use case would be one-time work (e.g. need a static website for my shop) AND willingness for the employer to pay using Bitcoin (or other 'safe' method as you describe it). The overlap of those two seems very narrow, although the cost of an experiment to set it up is pretty low if you wanna venture into it.
