Yes- I am trying a Kasha Pinecone. The Kasha bracing has been so successful for me with standard tenors and baris that it seemed logical it would also be successful in a Pinecone. Here is my design.
The side sound ports are shown here on the wrong side. They will of course, be facing the player. the tenor Pinecone has more surface area on the soundboard than a standard tenor. with its concave maple back, I expect this uke will have great volume. I am using a cedar top. The tone should be rich and punchy. We will see, what fun it is to build an experimental. Who knows the result?

Here is the layout. The sound holes will receive a thin veneer bracing, the bridge patch will mimic the bridge above it, and the toner locations are shown in pencil. Notice how much of this soundboard will be vibrating. That is the secret of Kasha success.

Here are all the tone bars, shaped, sanded and ready to glue down. I may shorten a couple to make room for a sound hole patch, but this ought to work. In the meantime, I had other fish to fry.
I got the first coat of French Polish on Ali's tenor. Wow what interesting wood. I think it is going to look spectacular.
What do you think?
