Can you reverse engineer the instructions for the completed blocks? I would think it shouldn't be that difficult to reduce the block size and the units that assemble the block into a size you like better. You can then make more blocks to make the quilt. Instead of say 6 30 finished blocks you may end up with 12 15" finished blocks.
Then you would have your own twist on the pattern and probably ample fabric (I understand CT kits are quite generous). Another way to make a pattern/kit your own is to change the setting. You may have to supplement fabric for that or you may use much less. It all depends.
Hard to give suggestions without knowing what the pattern is.
