I have seen all of these DMR to other modes but no DMR to P25 on the Pi Star. I was wondering if there are any plans for this.

I don't know the answer to your question, but the cross-mode work is actually implemented by Andy, CA6JAU, the fellow who creates the firmware for MMDVM. You can find his work on GitHub: https://github.com/juribeparada. He might actually be a better person to ask your question, but I'm not sure how you can contact him, perhaps via Twitter? https://twitter.com/juribeparada.

DMR to P25, or P25 to DMR isn't possible as a cross-over option, it requires transcoding.

YSF2P25 only works because "VW" mode on Yaesu is very similar to P25.
