Hi all,
Came up with a few ideas the last 2 days I thought I would post them here. Use them if you wish. of course you will need to figure out the "hop chamber" and how to seal it and what not. These are ideas that cold involve a bucking or no bucking. That is the cool part. You get to design the rest.
This one involves a silicone disk. In this fashion is could be fitted into a chamber and the BB would force itself under it and then get get additional friction on the back side. This goes to the idea of a longer contact time. The black line is the barrel the BB is behind thee "nub". You could put it on an axle, you could cut it in half you could additionally load it somehow and that is without really thinking about it but I can come up with a few more and you can too I am sure.

This one is just a long contact patch. It can be fixed it it can be pivoted like a VSR there are literally a dozen things you can do with this. BB is at the start point the black line is the barrel again. Once again you have to design the rest.

This one is hard to describe so I rendered it real quick. The hole the BB and barrel go in is lower than the recessed groove. Or the groove is higher, which ever. I rendered the recessed groove round, it can be oval as well. The idea is the groove would contain a rubber ring that intercepts the barrel opening. The BB would have to squeeze past it thereby inducing spin. The arc of the recess would dictate how much contact across the top you have on the BB

Here is a W style design using o-rings over metal. the metal will need to be countersunk to hold the o-rings steady. You can add pre-load or tension or anything else. You can also use long or traditional length contact patches. Much like the silicone one in the first picture but this one gives you a split hold on the BB.
Scale is way off, but you get the idea. MS Paint sucks for drawing.

Looking at this I can combine several elements actually. This is in no way a complete list. There are dozens and dozens and more than 5 times that in variants and combos.
These ideas are there to illustrate that hop up can look different than the normal. Of course you need to design the chamber.
The idea is to envision a hop up design and then design how to make it work. This is different than traditional hops ups and try to make yet another nub variant for that design. There are very few options there, I think there is room to improve it.
People sometimes wonder what I mean when I say I designed at least 6 hop up variants that could work. This is what I mean. Except that in my current models I actually designed the chamber and seal as well. There are many ways to do that it is only limited by creativity and desire to do it. Rethink the design, come up with a concept to solve the problem and then figure out what it goes in and how to make it work.
There is no reason at all hop ups have to look and work like they do today with a nub variant, H, V W etc it is all nubs. There is no secret nub. If you want quarter size groupings it is going to have to be rethought. Forget mags and auto feeding, work that out later. #1 problem people have is trying to solve too much.
Check Craig's list locally in your town under services for machine shop or CNC. You can likely find someone who can whip something up from a Visio diagram if you have dimensions pretty cheap.
Use them, discuss them, add to them, or say how they would or would not work. Of course you would need to build something to verify what you say if you are being definitive.
Look at them, think what is possible.

Here is the housing I designed to hold and test all manner of designs.

Good luck and have fun!
