"Ever play/design a scenario going from Epic to Skirmish?" Topic

I have always been interested in putting together a scenario where players would go from controlling 6mm scale figures, until certain goals are achieved, events were completed, and locations accessed, at which point those forces would be switched to their corresponding 28mm versions on a larger table, with terrain scaled to suit. This would all be part of the same game/scenario. I was thinking I'd need 2 different sets of rules, and the more detailed skirmish level game would include a fun narrative and the final challenge where victory would be determined. To this end, I've been painting up a bunch of old 6mm scale 40k and other tiny SciFi stuff and matching it with corresponding 25/28mm figures and vehicles; converted and painted to match. There are some obvious challenges in game design trying to do this. I was wondering if anyone else had tried such a scale and mid game rules swap, and if so, what rules worked well for both phases? Hint: I stopped buying 40K rules 20 years ago and don't plan on going back.

Yes, I am fiddling with two levels of play for Cynthia Ann's War. Larger force game has each activation card representing a group of 5 or 6 up to a dozen or even 20 men. A hit removes a horse and rider, no details. The whole group acts as one in terms of morale etc.

But I want to be able to move down to where each card activates a single man. A hit is rolled to see nether horse or rider, and a d6 for severity, maybe even roll for hit location. So men can be wounded, able to shoot but not move, or vice versa. Or pinned under horse. Friends and enemies can try to rescue or finish off. So very granular.

That requires a switch in TIME scale too, if I resolve a close fight lasting seconds, while larger groups are frozenn in place until it is resolved.

It is more clear in my mind than in the written rules, so far!
