I think about this all the time. 
 
I have seen people fabricate 90° 'arms' made from all kinds of materials and then use the hanging kit with the light to hang from the bars.  Im not a huge fan of that look but it does the job  
 
I think, if the the day comes when I actually make the switch back to t5 then I would have something custom made for the job.   
 
I like the look of the AI EXT rail system so I would go for something like that, with a custom bracket to hold the light.  A kind of claw if you wish. 
 
Either way, would probably cost a few bucks.
