I suppose it is technically possible by a trick like ((rk2_state_t *)(s->state))->k2, but that depends on the stepper. For rk2 it might work. However, some steppers don't preserve internally the intermediate values for the one whole step (h). The source would have to be modified in order for this trick to work with those steppers.
I suggest that if it is feasible, you should evaluate your function at the points you want outside ODE routines.
