I have some extra 8g around OFC and not quite ready to do the big 3. Im thinking about just replacing the POS wire to the ALT and fuse block(trucks). Both seem rather small the others are at a minimum 4g.

I don't see how it would cause an issue.

I wouldn't replace the the POS wire to ALT with the 8g, but I would run them with the OEM connection.

If you're replacing the 4g with the 8g you're just going to create a bottleneck-like effect and won't get all the power through.

If you're not ready to do the big 3, then don't do it, you'll just remove whatever you're planning to install now and replacing it later.

you can always add wires, you don't have to remove existing wires

I'd just go to a shop buy some 4g and run it along the one that you say is thin. Minimum. Its best just to do it all. If you want to do it, there isn't a real reason why not to all at once.
