Hi,
I think the main problem is the soldering process. Picture one "with paws" is designed to get soldered with some kind of soldering process. The one without "paws" is designed to get soldered through a bath type of soldering, without direct contact to some kind of solder iron.
From a repair point of view, you need to check the overall height of version one. It might be possible, but even with a successful repair job, your cover will not fit, because the chip with paws is larger and has higher/thicker dimensions.
In theory you can clip those paws, but then you will have a problem of de-placed solder points. It might only work if the clipped paws are exactly positioned to the old print. Since a clipping of paws will leave a stressed and deformed contact, you will need to grind it down instead of clipping.
However, even if you manage to have a correct positioned grinded down paw in place, the soldering will be another challenge. You need to know exactly how much heat and power is enough or needed for not doing a smelting grill session to ruin the whole thing. Do you have the right high precision tools available?
You may want to give that job to a GPU/CPU resoldering contractor, that has the right tools and solder bath to do it.
My Nvidia m330 gpu chip was destroyed through years of hard sweatlodge gaming on my MBP 2010, so a contractor put a new one in for about 180 bucks two years ago. Works like a charm. I would most likely use a service like that in your shoes.
