Please consult an expert (it is unlilely that you have done)
You are likely to be left with no transformers.

In Dyn11, the phase angle of the LV winding lags the HV by 11x30 = 330 degrees with the corresponding phase (or leads 30 degrees); while in Dyn5, the phase angle of the LV winding lags the HV by 5x30 = 150 degrees with the corresponding phase or lags 150-120 = 30 degrees with another phase. In no case, you can connect it with having 0 phase difference in secondary side. So, it is not possible at all.
