Dilemma concerning game board size

I have a dilemma which i have not solved yet. I am working an a fantasy wargame which uses hexes of 4.3-4.5 cm wide (heroscape size) from flat to flat. Normal units are flat hex tokens and characters are placed on stands. Average army has about 20 units and 6 cgaracters. The ideal mapsize is 100by70 cm. 100% i would stick to the hexes on the map as for me hexes are best way for modern wargaming.
I want to make it a kickstarter project.

Now i see the beautiful artwork of my artist making the units and such i wanted to keep the hex size of the tokens to 4 cm. I dont want to make it smaller.
A large board like battlelore is about 56 by 82 cm which feels a bit to small for all tactical movements and such.

I have a few options please discuss them with me...:

1) as a gamemap i provide with a high quality poster or which is folded in the box. advantage is low cost and small weight = low postal costs. Disadvantage looks cheap and not sturdy if not glued on something by the buyer
2) as a gamemap i stick to the battlelore size and even reduce the size of the tokens. Advantage is that i stick to the game standard of quality folded maps. Disadvantage is that the tokens and stands artwork get not into full glory.
3)or i produce the same as above but for a size of 50*70 cm and deliver 2 of these maps.
4) or i deliver durable hex stencils which buyers can use themselves to create their own hex based maps. advantage is low postal costs but i requires some work from the buyer.
5) or i deliver downloads of maps which buyers could use to make prints themselves or send to a photocopy service in their own country. Advantage is save much money (no manufacturing of map and postal costs due less weight, and smaller box since the tokens and cards themselves are relativly small).

Solution could also be to make some stretchgoals on kickstarter but what would u consider the best stretchgoal order?

And what options do u see for this mapdilemma?
