That's very interesting! It sounded like the big problem with the Shimergo setup would be the front derailleur. I saw a few posts that shifting was difficult with a Shimano road front derailleur. Some people recommended a MTB FD.
What FD are you using?

I am running Campagnolo Ergopower levers on several bikes with cantilever brakes and 3 x 9 Shimano derailleurs. If you go this route, I find that the 2011 - 2014 Campagnolo Chorus levers, which are advertised as 2 x 11, work best. The front lever has 6 "micro" clicks that can, with careful setup, operate both Shimano double or triple road or MTB front derailleurs. The rear 11 speed lever can directly control the older Shimano 9 speed MTB rear derailleurs (but not the newer Dyna-Sys MTB derailleurs). I am not familiar with the newest generation of Campagnolo Ergopower levers (came out in 2015) so I cannot say if they would work in a Shimergo setup like the older 2011 - 2014 versions. Also, I would not recommend the Athena (or lower level) Ergopower levers. I had several fail. The ultrashift mechanism in the Chorus Lever is much better (in fact the Chorus levers are identical to the Record and Super Record levers with the exception of the brake lever which have the groupo name on them).
Don't think you need to change the whole drivertrain unless you are unhappy with your current gearing.
Good Luck. The Eggman.
