millvolt + 24v on same t-stat

I currently have my 750mv boiler and my 24v AC running on the same t-stat (honyewell VisionPro) The steam boiler is on R and W, and the AC is an Rc and the other correct terminals. The jumper is removed form R and Rh. All is working.
Question:
Can I cun the 24v common from my AC to the t-stat to power it? Or will this not work since the R is hooked up to the millivolt. Any thoughts? It works fine on the batteries, but would rather power it from the 24volt if possible.
Thanks!
