If ship-jumping started with the progressive changes to the Church put in place by Vatican II 50 years ago, why do you think that even more extreme forms of those progressive changes will fix the problem? Isn't that just more of the same except in degree?  If the Church follows such, eventually, she will be an empty ship as you say the jump rate is staggering. Why come to mass at all if its not a necessity. It's boring! We've already seen that making the the Mass 'entertaining' to fill the seats can not possibly compete with the non-denominational protestant mega church "services". Protestants will always do easy-believeism worshiptainment mercy Jesus WAY better than Catholics.  I mean they only have to pray one prayer, ever!!  The more Catholics get a taste of worshiptainment mass the more they leave for the Mega church with it's on campus coffee shop and in-house Barnes and Noble, amazing music, creative youth activities and 'one prayer and that's it for life' liturgy.
