Turning this round bag -- can it be done?

Don't know for sure, but I do know it won't turn at all if you don't open the zipper before you stitch that last side on.  Don't ask me how I know....

 

It may work, considering the zipper opening is rather large, and the gusset is pretty large.  You'll just have to take it slow and work it.  You may get some bend marks in the tooled sides that you didn't want...

Heh-- luckily, I anticipated that being a problem, so I made sure the zipper is open before starting on the last side! 
It will be a slow process, I bet.

what R paper staples?

Regular staples, like you use with a stapler in an office.  If I've got a tricky assembly, like with a gusset that's hard to hold in place before sewing, I often use a stapler to staple the assembly just outside of where I will stitch.  That way everything stays perfectly in place while I stitch and then I use a staple remover to remove them, or if far enough away from my stitch line I just use scissors to reduce the seam allowance, thus cutting them off.

Well, folks, thanks for the input! I didn't have to use temporary stitches or staples at all! 
I just finished the stitching, trimmed the piping down, dampened the leather, and turned it inside out!
