Sure that can all work. I made a tank that's started like Tivoli with the mesh insert from Green Gables (they start similarly anyway) and the lace trim on the bottom from Soleil, or some other lace. And I combine patterns all the time - the shape from one and the st patts from 1 or 2 others. I'm not familiar with the patterns you mention, but just dive in and see how they work. Tou should be able to tell by the time you get to the sleeve division and if it doesn't seem like it's going well, you can start over and you'll have probably thought of other ways to improve it to get what you want.
