Member desires unusual vote requirement

[PBix]

Although an organization usually adopts motions by majority vote, a member proposing a motion on a controversial topic would like the motion to pass only if it has strong support.  Is the member free to propose the motion in the form, "Resolved, by vote of at least 3/4 of those members present and voting, that the organization shall do X"?  And if the motion is made in that form and then a majority, but less than 3/4, of those present and voting vote in favor of the motion, does the motion fail?

And if the form suggested in the OP would not work but some other form would accomplish the same goal, please indicate what that other form is.  E.g., perhaps the member could include in the body of the proposed resolution the phrase "this resolution shall be inoperative unless adopted by vote of at least 3/4 of those members present and voting."

I think something along the lines of the second form you have suggested will work.

There has been at least one lengthy discussion of this question before, and perhaps someone good at searching will come up with it.

Maybe this is it.  I found it when I saw PBix's question.   https://robertsrules.forumflash.com/topic/9171-modified-voting-basis/?tab=comments#comment-32523
