good idea !

I have a 14L pan and want to do a 10L brew is it ok to do the mash with 12L of water, and when it comes to the boil part have a second pan of boiling water to keep the wart topped up over 10L.

Yes - go for it!

Stating the obvious, the more water added, the more you will reduce your OG

If you wanted to get clever about it (a bit dangerous I know) - calculate your boil off rate - i.e. boil a pan of water for an hour (or 15 mins and times the result by 4) and see how much water is boiled off. Use that in your calculations re how much to start with at the start of your mash

Whatever - just brew some beer!

Good luck

I get about 8L from my 15L pot. I’ve tried to get more but find with more grain my efficiency suffers and I still end up close to 8L

Why not mash in your 14l pot, get the water in the other pot up to temperature and transfer the grains/bag at the end of the mash to batch sparge in the second pot. That way you'll be adding wort into the boil rather than just water?
