No i don't think that the question owner should get the percentage of upvote because from this the people will less focus on answering the question and they may prefer  to write more question and if fewer answers will come then they cannot beat and musing will not be able to achieve his dream of making the first decentralize app on steem platform.

As if this feature will come then there will be fewer chance people will only prefer to operate fewer answers and write more question and they will spend less time on musing platform as question takes only a few seconds to type and post on musing while answer takes more than 5-6 minutes to learn and give correctly the answer to the question. 

And there will be no proper answering of the question and if the percentage goes with the question owner then I think there will be more commands and more team should be build up in musing for the upvote and this may be lack of power of musing and wastage of power will be there for musing.
