Is it possible to judge from a first development only what the appropriate time and amount of hypo is for a particular film?

It would shorten the experimental cycle somewhat if one could simply run short lengths of film through a first developer, using differing amounts of hypo, then inspect to see which combination has the best potential.

What would one be looking for in a negative after first development that would indicate that it would make a good quality reversal?

Or is this akin to suggesting one would have to be looking for something that isn't there yet ?
