Does duoing with lower MMR lower your own MMR? It lowers your the MMR you play in, but I don't think it lowers your actual MMR.
Does duoing with lower MMR still let you promote twice? How much LP do I get? You should still be able to promote twice. Your LP gains and losses should also be still be normal.
Can I dodge 14 times to demote? No, you will reach -100 LP eventually and cannot go further than that.
