Adding an integrator for your own work is hard but doable, especially if you don't need it parallelized. Look at the do_update_X routines for examples. It will be harder for 5th/6th order since you probably need values of the forces for times in the past, which are not automatically stored in gromacs -- you'll have to add arrays to store them yourself (which will get rather hard with parallelization).
Adding something that other people could use as a general release -- probably not something you would want to try now. Some plans in the works to make it easier, but it will be a few months at the soonest. Just wondering about adding predictor/corrector integrators. They tend to be quite bad over longer time scales. Is there a particular reason?
