In your first post here, you mentioned looking for an all-mountain ski which would suit your needs and your more aggressive skiing style.
What happened to that idea? The difference between the skis in your photo and any of the ones on your "list" will be astronomical on the slope.
The money you'd spend retrofitting those straight sticks to your boot (your newer, fitted boot, yes?) will be better spent toward either a new ski or a season demo / rental ski program to figure out what you like personally.
Besides, the bindings on those sticks may not even be indemnified anymore and then you're out the cost of new binders for a pair of skis that is less than ideal for you.
I'd strongly suggest leaving those skis to decorate the garage and finding something newer which will be so much more enjoyable, and which will help get your skiing back on track immensely.
