I can understand where you are coming from and therfore see why you think the 'morph brush sucks'  but in the wider scheme of things I do think it is a little harsh.  Many tools both in the workshop and 3D suck if you try and use the wrong tool to do the job in question.

I admire your ambition but to build a morph that is based on a real person that is not only accurate but built to the level that it will sell seems a tall order.   I am not at level where I can assist as I would not even attempt such a project but others here, who have proved they know what they are on about, have offered their opinion and help.  That is a big plus but it does not negate the need for you to put in the hard work. 

My Grandfather, who I admired so much and has been dead many a year, often used the saying a bad workman always blames his tools, something I think you may be a little guilty of here.  I mention this not to be cruitical of you but because I do not want readers to think that the morph brush sucks in general, but I accept it does not do what you want it to do.

I have already said that this type of morph would not interest me but that does not mean I am not interested in the what you are doing and I wish you every success .
