I'm not sure modifying existing designs is even a thing. Each element requires a certain amount of space based on it's diameter. Start increasing the size of the elements and everything else is going out of whack. It's probably better to start from scratch in many circumstances.

What do you own? 3 lenses, and you have all three of them with you all the time?

After all, the biggest factor for when a lens gets used, is "is it with me when I need it".
