It's a great idea, but it's also a HUGE project.
In reality it would probably need to be something we take on as a custom job to be sure of the payoff - it's a fairly niche mod, would require a TON of work and would have to be sold at a reasonably high price, not to mention the complexity involved and the fact pretty much every sport would have to have it's own set of inputs and rules and score grabbing facilities...
It's unlikely to be done unless a serious site comes along and commissions it as a custom project really.
