WTNW Skirmisher Question

I was just talking with my friend about skirmish games and rank and file games. The WTNW Saving the World Just Before Tea is shaping up to be a game in which one can run units or simply play a few individuals on a table but it is kind of at a crossroad and to continue forth I need some input.

The Pulp Alley game I wrote with David Phipps back three + years ago was more of what people consider 'skirmish games' but what I am wanting to do with this is to write a game that uses 1:1 scale and is playable similarly to 40k or Warmachine. Right now there are three rolls. Roll to hit, roll to save, roll to wound and each step figures modifiers for different elements.

For instance, before rolling to wound a target with armor, an attacker calculates their adjusted weapon strength score based on its armor penetration value compared to the target's armor value and when rolling to save a unit calculates the effects of terrain. This can all become very cumbersome to calculate but each degree of realism adds an extra element to the game.

What are your thoughts on skirmish gaming? What would you like to see in a WTNW skirmisher game? Do you want 1:1 with only a handful of guys forming a league or troop or would you rather have a game that uses 10-12 man units? Your suggestions are welcome and are appreciated.
