Thank you for your perspectives as always! I actually never use a xylo or a glock in this piece but there is a Celesta. The rest are pianos layered with effects to create a sound very similar to the the instruments you listed though. I think it helped soften the sound but still give the ringing tone of those instruments.
I'll try and give some personalization for Melody and other things too in the future. As seems to be my call, I like to uhh, stay in the lines when I make things initially. I need to learn to spread my wings some more!
