I doubt road long reach would make it. To do this, and I think it'd be stupid to do so, you'd need something the size of a BMX caliper. There's a good reason that calipers have been relegated to lower end BMX bikes, what issues are you having with canits? Maintainability? Calipers are a PITA.
I just went out and checked my Fantom CX in the garage, yeah, no way in hell you'd make it with a road caliper.
EDIT: TL/DR you're both crazy and stupid.
