Well that project just came to a stall. Had my contract at the house yesterday and told him what the plans were and after a little investigating in his part found the remote sump is a no go I would have to drill two holes through the header. He said sure go and do it but the inspectors aren't going to be happy about it.
If you cannot go through go around...that sounds like a good plan.Main beam....although there are situations were it could be drilled.....small holes....especially if it's LVL (laminated), I'd stick to running under the beam and simply boxing it in. I'm assuming you are going with a finished basement. You won't even notice the box in. I did it with the entire loop of pipe for my heating system.
