Using decals from model kits on Yamato Valks

[Schismatrix]

Does anyone have any experience using waterslide decals from Hasegawa or Wave injection kits on their Yamato 1/48 Valkyries? I know the scale is different but it seems like there are several different sizes of key markings (like skulls and that UN Spacy"kite" insignia) so I was wondering if anyone had had any success using, for example, the largest skull decal from a 1/72 kit to replace the smallest skull on the Yamato 1/48 sticker sheet. Does this make sense?

There are tons and tons of decals available for 1/48 military aircraft so the generic markings anre't a problem. It's the Macross specific markings that are a real pain because I don't think there were ever any VF-1 kits produced in 1/60 or 1/48 scale (am I wrong?).

Anyway, my quest for decent decals for my 1/48 Valks continues so any input is welcome!
