Seeking Tin whistle riffs, fills and solo in the Key of D

This song is 175 bpm in the key of D at 3/4 time. It's got a basic 3-chord structure mimicking an Irish folk ballad. My original idea was to marry the traditional form to a Bo Diddley type rhythm, but with the 3/4 beat it is taking on personality of its own. I'd like to hear a tin whistle weaving around providing riffs and fills--becoming especially active during the third and forth verses
