Let me see if I’m following … you’ve made modifications to mipsopf_solver.m and 
you would like them to be used by the DC OPF as well as the AC OPF? If so, 
unfortunately, that is not possible. The mipsopf_solver() function is specific 
to the AC OPF formulation. The standard DC OPF formulation results in a simple 
QP or LP problem that can be passed directly to qps_matpower() to solve using 
any of the available QP/LP solvers.

Do your modifications to the DC OPF problem still result in a QP or LP problem? 
If so, you should be able to make the modifications for the DC version right in 
dcopf_solver().

Hope this answers your questions,
