Go for it. The beauty of open source is that you are free to
try things. I would submit your first step of learning is how
to figure out where all the -O2's are. You will learn a lot about
things if you really dig into the weird problems you will hit.
Probably you won't get much help here, but that shouldn't
stop you. Hint: start reading about compilers.

Eh, I run it on a VM. I could copy one and somehow locate all the -O2's and
replace them with -O3's in the files. I'd probably have to write a program
to do it, unless there are easy to find, centrally located ones?

Do you have the skills to detect and handle if gcc miscompiles something
at -O3?
If not, then don't.
Noone else will help you getting a zomg-fast -O3 system working after a
slight miscompile gets a few bad instructions stuffed into some lib
somewhere, so if you break your system, you get to keep all the pieces.
Short version: "if you had to ask, then the answer was no".
