Upgrading logic board in Macbook Pro?

I've bought a broken MBP (on and off video output to screen, suspect logic board failure) and was wondering if the newer logic boards are backwards compatible at all (bodging something is also fine, I'm fairly good at working on the internals)?
It's a 17" 2.33 C2D model (06/07?) and I was looking at the newer 17" 2.5 C2D boards (08?).
Any help much appreciated, thanks.

More specifically it seems I'm trying to put an A1261 board in a A1212 machine.

In general, the answer is no, although I don't know about this specific case. In addition, consumers can't get their hands on replacement parts. Even if you could, they're not cheap.

It looks like it's just an overheating GC, so might try a simple fix instead then.
There are plenty of donor machines around with cracked screens that I was going to use, just wondered if the board design changed much, etc.

Not too much no. Just enough. Some of the 2008 17"s had LED displays, if not all of them. The inverter board in yours will not connect to a logic board that expects an LED driver board to be attached which means you'd need to swap out the lid for a newer version too.

I have plenty of more important things to do, if only I could bring myself to do them....

Does the same happen with an external screen?
