Will Shift Kit work with internal hub transmission?

[5-7HEAVEN]

To place the 1.463:1 pedalling ratio into perspective, on my motorized bike, I have used a 22t chainring and a 32t rear cassette sprocket(1st gear).This computes to 1.45:1 ratio...

My engine LOVED it, because the 1.45:1 ratio created a ultra-low gear ratio of 41.65:1...brute acceleration! I was able to utilize this gear because of my GP460 engine's 11,000+rpm capabilities.

Shifting at 6,000rpms, HT engine, bike speeds with the 1.45:1 ratio are 11.1mph/14.7mph/19.6mph...

If using 29.8:1/22.42:1/16.93:1 ratios, bike speeds of 15.6mph/20.7mph/27.4mph...

If using 23.83:1/17.92:1/13.45:1 ratios, speeds of 19.5mph/25.9mph/34.5mph at 6,000rpms.

In comparison, gear ratio Of Happy Time with 44t is 18.26, with speed of 25.4mph at 6,000rpms...

With 36t, speed of 31.1mph at 6,000rpms...

A ratio of 13.45:1 is similar to a 32t, with speed of 34.5mph at 6,000rpms...

HOWEVER, when trying to pedal in this gear, it was great if climbing a very steep hill.

On flat ground, someone walking alongside you would be travelling faster than you if you were pedalling in this gear.

Totally useless for pedalling.

Now, it is quite possible to build an FD system that would be capable of at least two, and possibly more speed ratios, and "shift in motion". It isn't even all that complicated to do.

Can this type of FD system be elaborated further ? Has anyone ever attempted a build like this ?
