ooh, that’s even better than what I came up with. @apoorva6262 and I discussed this during office hours today and I suggested
data = epochs.get_data()
pseudo_raw_data = np.hstack(data)
pseudo_raw = mne.io.RawArray(pseudo_raw_data, epochs.info)
new_epochs = mne.make_fixed_length_epochs(pseudo_raw, duration=1.)
