[REQUEST] Random combinator

[gustaphe]

I am aware of the Useful combinators mod, with it's random combinator, but I would like a more robust random combinator:
Shaped like an arithmetic combinator. Takes each input and uses it as seed for the output, so if I put 1 iron ore, 12 copper ore and 1 raw stone, I might get 100 iron ore, 4 copper ore and 100 raw stone back. (NB the same value for iron and stone)
Possibly with a field to assign a maximum value.
That way, if I want it to generate a new number with a special time interval, I do the same as I would while making a clock out of arithmetics and deciders. (eg. a random combinator plugged into itself would generate a new number per tick)

I'd make it myself, but I can't find any mods that use two-sided combinators, so I'm starting to fear they aren't that easilly moddable.
