As for 'making the handling more stable'. Oh boy, are you in for a shock. The reason no normal human can 'track stand' a recumbent but tens of thousands of ordinary Cat 5 road racers can at least approximate it on DF bikes is because the higher your eyepoint above your center of gravity the easier it is to find the balance equilibrium. You have much more time to react to the forces trying to destabilize you. Don't be in a hurry to sell those 700c wheels.
I don't know why you have to be so condescending and hostile.
1. My legs cannot reach the ground with 700cc wheels; hence that configuration is more unstable for me. Further, lower and smaller wheels are not as susceptible to cross-winds as larger wheels.
{edit: don't know why I would want or need to trackstand on a bent and FWIW, several people report the smaller wheels are more stable in the corners**
2. I did not simply switch out wheels; I also substituted a shorter fork, meaning the weight distribution WILL be biased more forward because the front end will be lower than it would be with a standard 700cc fork. (yes, I understand this also affects trail)
3. Regarding wheel base, I will give you that if measured from the center axle, it will remain the same, but smaller radius wheels mean the distance between the points of tire contact on the ground should be greater than with larger wheels.
