Will 2 x 10 speed front derailleur work with 11 speed set up?
11 and 10 speed cranksets have slightly different chainring spacings to accommodate the difference in 11 and 10 speed chain widths. Front derailleurs have slightly different movement also.

You have a matching 10 speed front derailleur and crankset, so really the question is whether an 11 speed chain will work on a 10 speed front. I think from past answers I have seen here it will work OK.
