Supporting Ridge Beam Post with LVL?
I think you need a structural engineer to sign off your designs before you start cutting structural timbers.  However:

There is no problem in principle in running a suitably sized blue beam to the right of the current post.  What you may need, is a post running from the blue beam directly up to the ridge. This would leave you the completely open space at floor level, but would be visible in the open space above the beam.

Does the existing post run all the way to the roof?  If not, you won't need one in the new scheme.  If it does, you will.
