Well that's great you want to be different. Go ahead and do it.

I've just seen a lot of people attempt something that complicated without knowing what the hell they're getting into. Then they quit.

My point in a nutshell is this:
Nothing will just "fit," you'll have to make EVERYTHING fit.

Nothing will line up, and bolt in. You'll have to figure it all out.

None of the wiring will work. You'll have to custom wire the whole thing.

None of the driveline components will mate. You have to build all of the mounting points.

The jag engine WILL need a jag transmission. You hope it "fits" in the Merc's trans tunnel.

Oh, but it won't match any mounting points either, now make those too...

If you can accomplish such a swap, it'll be one of those things where everyone who has ANY idea how much work was involved will appreciate it with awe.

First thing you need to do, is get complete, FACTORY manuals for the merc and the jag. NOT THE CHEAP HAYNES manuals, they will NOT have the detail and specific info you're going to need.

You need explicit schematics of the merc's enitire drivetrain, and the jag's too. That will enable you to start planning what parts you'll have to make.

Find a damn good machine shop. They're going to get a lot of your cash, so don't waste it.

I'd like to know, just out of curiosity, what's the most complex auto mechanical job you've ever done?

Have you ever swapped an engine? Removed one, rebuilt it, put it back?

Luck.
