There have always been two historical challenges to a Destro build...
The CG has always been a big one. Most Destro reps had the CG lever closing the wrong way - even DSN.
Now that lathes are in the workshops of guys like Ziggy - custom CG pins possible so flipping and reshaping a nice CG to perform Destro is possible.
The second challenge is always the dial. If you can find a good Destro Sausage lumed dial you can do a 22.
As has been mentioned, Little Hero made a nice Sandwich Destro dial so you can make a 219 like the one HackR mentions above.
The 239, as Toad mentions, is a good one in a Submersible, if you can find them.
I found a nice dial a while back and made a PAM 026B (Lumi Dial) - and DSN sells the more modern re-release of the PAM 026 with the sandwich dial.
Here is mine:
