Crank is a mountain triple, so chain line will be off, it's also a MTB front derailleur which won't work (well) with brifters. Wheels and rear cassette will work, although most brifters these days at a low price point like 105 are all 10 speed so the casette is workable.

Brakes are V's? No good with brifters. Easy swapover parts are wheels and rear derailleur. I don't see value in stripping down the FX for that.

There are ways around stuff to make some of the other parts work, but it's still going to be frankenbike'ish. I'd buy the CC frame and pick up parts as I could afford, once it's built then look at flipping the FX as is to put $ back in the piggybank.
