Everything Wolph says can be done.
But, really, this is seriously over-complicating a simple random encounter roll.
Just make a macro called "Random Encounter Roll" and throw it on the "Party" token. Move the token, and then click the macro when you want to check for a random encounter. Chances are you aren't always going to want to roll a random encounter anyway.
This is probably your best way to go. Besides, in most game systems, it's more of a factor of "time" vs "distance" for random encounters. I have players who move the token 10 feet, then over 10, back 10, over 5, then up 30. Either because FoW or just poor mouse skills. Does that warrant 5 checks?
NOW, if you were having it roll a "Perception" check or something to see if said token notices or is noticed by tokens, that's another ball of wax. It can be done for sure but it's a few lines of code...
