Extending battery cables?

In the past I have made a crimp connector out of a piece of copper pipe and used a propane touch to melt some solder around it. Crimp it with a punch and a hammer.

Nothing is too big to solder. Seriously, torches come in a wide variety of sizes.
You can buy lugs as large as you need to. If you don't find any at your local auto parts store, go to the local welding store. You can squash it in your bench vise (it's called swaging) or with incrementally tighter settings with a pair of vise-grips.

Stock is 2 guage?..... They didn't look that big to me.
Longer batt'ry cables are not that expensive. I just put some longer ones (38"/ 4 guage) on my '86. Cost me a total of $14. They go about $1 higher the longer they get.....at O'Reilly, anyway. Can't imagine it being much different at any other discount auto stores.
On the other hand, splicing them will work. It's done all the time on high voltage applications. The thing to do, though, is secure the splice to a stationary location so the splice can't pull apart/loosen. And seal it well with splice tape, rubberized coating, heat shrink, etc.

I said "IF stock is 2GA..."
It's probably more like 6GA, but that's fine.
If you are going to splice cables, fill the splice and the cable with something like No-alox or kopperkote to keep corrosion to a minimum. Personally, I prefer the former since it's designed to work with different metals, particularly splicing copper to aluminum or tin, or various combinations of....

OH! silly me......gerf
No-alox is good stuff. I've used it a lot when I had to fix a few splices in the main feed to the house years ago. Then, I just rewired the house from the main pole to the new main panel I put in. Butt splices and shrink tube are better than bolt splices, fyi.....<<<anyone<<<

I will attest that I've seen terminals bolted to a buss bar within .5 miles of the ocean that have 0 oxidation at the point of contact when no-alox or kopperkote have been used, and the copper bar surrounding the connection have been covered green by cupric-oxide.
So, you know that end of the deal.
And if you're gonna heat-shrink, use marine grade heat shrink since the shrink is lined with a compound that flows and seals gaps.

There is one splice in the 200amp, 4/0 ground wire running to the house (don't ask why). I used a butt splice and that type of heat shrink. That stuff is fantastic. I didn't realize they had it any smaller. Hmmm....

Why not just buy a relocation kit with a longer positive cable? It still grounds to the frame at both ends of the vehicle (battery to frame in rear, frame to engine in front). Are you putting it in the rear somewhere or just a "little" further away from where it is now?
