Wow thats the best Shot I think I've ever seen of it, but no one has tried to make one yet to my knowleadge. I don't think there is anything in the CRL's aginst it, but in universe wise, the jet pack would be over three thousand years old. I don't think any mando would use a piece of antiquated tech like that, especially with the luck the Fetts had with thier newer models.
No reason you couldn't try your hand at building one though, I'd recomend the old Mego Blocks scuba set to start with as a base. Or if you knew of someone that makes steam punk rocketeer packs, as it in deed does look very similar.
Have a good one,
