I have data.
I have a Starlyte. It is the variation without the pot stand. I'm using it with an Olicamp XTS pot. That is a 1 L anodized Al pot with a heat exchanger bottom. I made a pot stand out of hardware cloth and a wind screen out of Al flashing. I put a piece of foil and carbon felt underneath to reflect heat, insulate the stove, and protect the surface.
Are you looking for power or efficiency? I define power at the rate at which the water is heated and efficiency as how much heat goes in the water per gram of fuel burned. I doubt that you will gain much in efficiencies, unless you go to a propane canister stove, because you have a center-burning stove that doesn't need priming. Alky stoves that need priming lose efficiency because fuel burned when priming don't heat the water. Side burners lose efficiency if they send too many flames up the side of the pot. The one thing that may help you is a pot with a heat exchange like my Olicamp XTS. I would like to try my system with a TI pot to measure how much that exchange helps. I can say that I can feel very little heat coming up the side of the pot while heating and while burning, the wind screen is barely warm. I assume from this that my efficiency is near optimum, so I have focused my tests on on optimizing power.
What you will find with this stove is that the heat output (power) dies out as it runs out of fuel. You see in this post (link below), when I put a full load of fuel in the stove (about 45 mL) I got a boil of 2 cups in just under 5 minutes. With 15 mL of fuel, the power was much lower and it didn't quite come to boil after 7 minutes.

If you scroll down on that thread, you will see another graph that show how I calculated the power as the stove was burning out to be about 60% of the power when fully loaded with fuel. An advantage of the Starlyte without the pot stand is that it has a plastic lid. That along with the fuel absorbing wick means you can load up the stove all the way (almost 50 mL), burn until you are done, blow it or snuff it out, and put it away with the excess fuel still in the stove. No need to measure or guess how much fuel you might need for your meal.
Here is another thread about my system from when I was just getting started.

My system isn't lighter than yours, but if you were to swap out your Starlyte for a Starlyte with lid and pot stand, you would gain some versatility, convenience, and power (with very little weight penalty). You might get a bump in efficiency with an Olicamp XTS, but with a bigger weight penalty.
