As I'm sure you know, Von moved to DE fairly often on passing downs. The point of this was to increase the number of effective edge rushers from one to two. Now, you want to do the same, but the result will be to increase the effective edge rushers from zero to one. Not something I'm excited about.
Also, Von's effect on the game will decrease tremendously if he is taking on an OT every play. Not just against the run, but also rushing the passer. A lot of Von's success came about because the offense didn't know if he was rushing or not, so they couldn't fully commit a blocker to him, let alone double team him. If he's at RDE, it will be easy to double him, leave everyone else single blocked, and then pressure will come from... where?
