So, would the planets be represented by land, and space by water? Then spaceships could be aquatic. The troop carriers could grant "water breathing" to the units they commanded, hence allowing carrying troops through space. However, the troops would then be present in space combats. The only solution I can think of to this would be to have spaceships vastly superior to troops, so that troops fighting in space would be largely irrelevant (as you'd expect if troops were floating around in spacesuits, although that still doesn't explain why they got out of their transports in the first place).

The stats will look very strange on spaceships. Strength and magic resistance at least. Most of the rest are probably okay.
