syntactic analysis - Better sentence structure - Inversion sentence with should

My original sentence is:

Should the doctrine of democracy be proved to be an important and effective mean to control the government, it should not be reformed insofar as the effect of which is to limit the effectiveness of it

I am not sure if the sentence is grammatically correct.

Do you think "should" is a better choice than "if" in this sentence?

Having considered some of the comments below, would it be better if I put it as -

Should the doctrine be proved to be an effective control against the government, any reform that might undermine its effectiveness would be undesirable

Thank you so much
