Optical bay to hot swap bay adapter? Not sure if its a thing

Hey guys.

I'm not sure if this is a thing so don't crusify me if I'm stupid for thinking there might be. Anyway I'm building a mini itx gaming PC and the case I am using is the Lian Li case Logan revied and used to build a mini itx gaming PC for LAN parties; I won't need a optical drive so is there a 'adapter' which I could slot in the bay which would act as a hot swap dock for my 3.5 inch hard drive? I don't need those 4 machanical drive bays and if possible I would like to remove them, I have a GTX 660 Ti GPU so I can't mount the hard drive on the bottom so that hot swap bay thing would be ideal. 

Hope what I've said makes sense, thanks in advance. 

There is such a thing for a hot swap 3.5 inch bay:
