The Fermi break-up model is designed to describe "explosive" nuclear reactions, rather than the single neutron removal channel you consider. C11 and O15 are created mostly in peripheral pC or pO collisions, where the residual nucleus recieves low excitation energy. So your plots look really strange !

GEANT4 v 8.0 (patch 01) seems to be good in describing beta+-activity distrobutions induced by 62 and 110 MeV protons in PMMA. Details can be found at http://lanl.arxiv.org/abs/physics/0507091, also Phys.Med.Biol., 2006 in print. Our physics lists are similar to TestEm7, with addition of RaddioactiveDecay.

Are you able to describe 62 and 110 MeV protond data by Oelfke et al 1996 ?
