after giving those one measure each twice, I think there's space for more minor chords... so I went all out:
D, F#m, Em, A7
D, F#m, Em, A7
Bm, F#m, Gm, Am
That's a verse, leading into a pause.. then the next verse, or into a chorus or bridge. Good luck
/edit: For some reason, the progression reminded me of Men At Work's 'Overkill', you might like to check that out...
