Cheapest version would be to get some kind of mod that overwrites dice imput and let you give them any value you want ...
Wich should be possible since i remember during one Panel From Hell, one of developers kept presing 1 ... and Swen was rolling all 1 ... not sure if that was part of the game, or some showcase tho (its years ago ... hslls, now i feel old). :-/
Then you would roll your physical dice and simply tell the game what you rolled.
Its not ideal ...
But it would be cheap and 100% doable!
I quick searched, and manual rolling mods are quire requested ... so fingers crossed, if that would interest you.
