Corroded copper baseboard heating pipes going into slab - critique my repair plan?

Picture of the pipes in question.

I guess there's sulfur somewhere nearby that's corroding the pipes (there are two of them, sort of hard to see in the picture). Lucky to get through the winter without it leaking.

My plan is the following:

1. Remove quarter round in this hallway to access the Pergo and remove that
2. Drain the system
3. Bust up the concrete near those pipes, exposing them, and go a little deeper if possible
4. Remove the pipes (cut them above ground and remove the whole pieces)
5. Run conduit where the pipes are so if this happens again or needs to be re-piped for any reason it isn't a huge deal (flexible nonmetallic conduit)
6. Run PEX through that conduit and SharkBite fittings to the baseboard above ground
7. Fill in the concrete, re-lay the floor and put on the trim

Anything I'm missing or should look out for? This goes into the concrete right at a doorway.
