Well, in those conditions, i fear it will be impossible to unite us in a mutual agreement of what we really want.
So i would like to propose something else, a variant of what you're proposing.
If we can't agree on a big production (an entire army or filling gaps), why not, each year, order ONE fig, to celebrate our range ?
It would be a limited edition, maybe 100 exemplaries as an example. We pick something missing in one army, we find the sculptor and let's go.
We have good sculptors, here. I'm thinking about Bell, David, Evil and Chaos... And loads of others.
We could change each year if we have too many sculptors.
This is a smaller task than what you where proposing at first. Easier and simpler, and cheaper too. A good first attempt of creating our own stuff i thing. More reasonable.
And easier to reunite everybody around one fig for one year. Next year will come quickly, and if we don't do the fig you want today, it may be next one.
