I'm afraid the Hex Stands cannot be connected directly to a baseplate--doing so would require stud notches cut into four of the sides the way many Lego wedge plates are designed. While this would expand their usability a bit as a part for building, I opted against this kind of design because it would look ugly while not affecting their usability on a 1" hex map.
Even if they had been designed this way, you would still be constrained by Lego geometry to the same 90 degree angles as the stud grid--defeating the functional purpose of a hexagonal stand.
A little background--I originally raised this idea with Will because for years I have played a homebrew GURPS variant with my friends where we use minifigs on the hex map for combat rather than traditional miniatures. Minifigs are endlessly versatile and can be assembled and reused on the fly without the need for paints or the other overhead associated with gaming miniatures. These stands are like a dream come true for us, and it's become obvious that there is a market for them beyond just our own needs.
Adapting BrikWars to a hex map would be trivially easy--everything in BW is measured in inches; translate this to "hexes" and you should be pretty much good to go.

Thanks! That is exactly the purpose of those hollow studs. We started out just using a red tile there to indicate a player was at half-health, but the possibilities are endless. Health and power tokens, status markers, squad(ron) colors, or anything else you might want to have at a glance on the map. And of course for games that don't require any markers like that, or for showing off your minifigs, the two-stud version keeps things simple and clean.
