changing a bodysuit padding help?

So I'm updating my snow leopard' s bodysuit.
She has digigrade legs. It's stuffed pillows sown to the suit.

As you can kind see, the thigh padding is huge, and the calf padding sticks out to much, and there is no follow between the knee to calf.
I would like to change it by making the knee padding smaller, and fixing the calf' s.
Do I need to just cut the calf' s off,  And sow new materiel with the padding back on?

Or.

I wouldn't mind changing the bodysuit just back to a plantigrade one. I saw a post about this along while back but wouldn't know where to look.
Anyone know how I could change the seems?
