I have to agree with the above. Anything is possible if you have a solid understanding of electronic engineering and how circuits and components work but it won't be easy.
I do think that you have a bit of confusion on how modding a computer works. In the old days we had jumpers that we could use to "tweak" a computer (speaking PC here but the concepts are the same) which could trick the processor into running faster. This is called "overclocking" and it makes the processor run hotter. The idea was to push it to the edge of stability to get the best performance, much like people do with a stock engine of a car. However, these jumpers were removed and replaced with a software type of system called the BIOS (still PC here). You can still overclock but now the software handles it. There are various things that could be done on a PC front but I think that MAC is locked pretty tightly (I'm sure that I will be corrected on this if I am wrong).
What you are asking is to basically take a faster processor off of one board and putting it on a board that was not designed to run it. The short answer is no, it won't work and you would have a ton of learning to do to even go down this route. To put it into more of a perspective, it would be like trying to drop a 400 big block into a MINI. Anything is possible but serious modification to the overall structure would have to occur.
If you are really interested in all of this you need to start looking at hardware level classes at a college. Terms like endianness and little man computer are concepts that you should know and understand to do what you are asking if this is what you were thinking. As a programming major and a former radio repair tech in the Army (circuit level) I can tell you that it is complicated and not easy. However, if you have gumption, then I say go for it!
Now, if you are wanting to repair an old board that is damaged (other than processor or specialized IC) then you might be able to do this with a little trial and error. I have repaired some older boards that blew capacitors but many boards today use very specialized integrated circuits that you can't buy on the market. This makes it hard to repair many systems. They also tend to take a lot of different things with them when they die which makes it even worse.
I don't want to burst your bubble on this but if you are this ramped up about stuff like this, why not learn some programming? It requires problem solving skills and ingenuity to get things done and you might find that you like it.
