Keep in mind that a -17 stem is 16mm lower than a 130mm -10 stem. OP, how tall are you and what's your inseam?
For reference, a Felt F FRD in sz 54 has a stack of 526 and reach of 389. A 56 has 548 stack and 397 reach. A Medium Cipo RB1K has 397.6 reach and 520 stack. So, there's still non-custom options out there. Oh, also, a 54cm Emonda H1 is close too at 526mm stack and 390mm reach.
