Mid 2009 internals into 2011 model?

I’ve got a mid 2009 2.53 GHz Macbook Pro from college that had snapped at the lid bracket. I went through alot trying to fix it myself and managed to ruin the bluetooth, wifi, and webcamera connection ports.

A new display assembly would be great but at $325 for C-Stock its not really in the budget. I managed to find a few A1286 models on eBay for $120, no HDD, no RAM basically just for parts.

My hope was to take the internals from my mid 2009 model and give life to a 2011 model while also upgrading the RAM to 16GB (or 8 should it not work).

Has anyone had any experience doing something like this? Is it as simple as pulling the HDD and other components and plugging them in?
