AI want to do a birdcage cake using 10 inch rounds. I would like to stack 3, possibly 4 using the SPS between each two layers. I would then like to carve a top cake for the dome. Is this too much weight for one cake? I would use a cake plate or board between the dome and the top two layers. SPS if necessary. Any ideas or comments would be greatly appreciated as I always tend to want to make cake defy the odds! Will be traveling about 30 minutes away with cake.

With the proper support it should be okay, the birdcage cake in my photos was 3 8" rounds (4"high each) and another 1/2 as high 8"round, I used the wilton wonder mold pan for my top, supported each 4"layer with cardboard circle and bubble tea straws then a centre dowel through the whole cake, travelled 2 hours with it no problem.
