You can graft plums or peaches unto it and it would be fine.
But here's the caveat. If you graft early bloomers or cultivars that leaf out quickly, make sure to graft them in the northern side because they tend to grow earlier and can siphon off the reserves and shade out the later bloomers or later growing ones if grafted in the southern side.
BTW, my Tri-Lite Peach Plum wine from my harvest last year is ready for bottling. They tasted wonderful.
