Glad to see you will be using our stands.
Actually, I ran an early Battle of Britain game awhile back, depicting the Luftwaffe raids on one of the British Coastal Convoys, using 1/144th scale Stukas, escorted by Me-109E's. The opposing side had Spitfires, and 1/600th scale ships, and it worked very well, and looked great on the tabletop, especially when the divebombers pushed over into the vertical.
Therefore, I see no reason why you couldn't use 1/700th scale vessels as well, since they are similar in size.
Using the two scales together just gives a bit of forced perspective of height, needed for some raids.
Good luck on the project, and feel free to let us know of additional details, and/or share photos of your dogfight, when you have the time.
Best regards,
Rob
