Possibility of use MG4 customized model in MG5

Dear experts,

We are trying to make the dark SUSY model customized in MadGraph4[1] to work in MadGraph5. Currently I'm importing "heft" model for production process pp->h and importing MG4 customized dark SUSY model[2] for higgs decay process in MadGraph 5, it is not working. The output[3] is saying the pp->h process is not valid.

However, when I just import the "heft" model and just keep the pp->h process, it runs fine.

Do you think it's possible to make MG4 model work in MG5 and how should I proceed?

Thanks,
Wei

load MG5 configuration from input/mg5_configuration.txt
fastjet-config does not seem to correspond to a valid fastjet-config executable (v3+). We will use fjcore instead.
 Please set the 'fastjet'variable to the full (absolute) /PATH/TO/fastjet-config (including fastjet-config).
 MG5_aMC> set fastjet /PATH/TO/fastjet-config

lhapdf-config does not seem to correspond to a valid lhapdf-config executable.
Please set the 'lhapdf' variable to the (absolute) /PATH/TO/lhapdf-config (including lhapdf-config).
Note that you can still compile and run aMC@NLO with the built-in PDFs
