Bad idea? Carbon steel and 304 stainless?
(OP)
Is it a bad idea to connect carbon steel and stainless pipe?
Room temperatures and mainly water.
I saw in a galvanic series chart that the difference in potential is about .4 and obviously the Carbon steel will get sacrificed.
Any coating that I could use between them?

Untreated, oxygenated water? Water with high total dissolved solids or low pH? It might be a risk.
Make the connection with galvanic isolation (galvanic unions etc.) if possible and you can take the risk out of it. Just don't connect them through the structure or with a ground wire etc. or you've defeated the usefulness of the galvanic union.

"You see, wire telegraph is like a very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? Radio operates the same way: You send signals here, they receive them there. The only difference is there is no cat." A. Einstein

Actually the galvanic series that you saw is in seawater. In water with low conductivity it is less of an issue. With Lake Michigan water you would not need to do anything.
