I learned x-foot hitchhikers by just practicing switch foot Karls until I could do them comfortably enough to swing my balance leg behind the other onto the opposite peg. For me it was a process of dialing the switch foot balance, crossing, learning to bail, then letting my weight onto the opposite peg and relearning to balance as I would double footed.
To answer your question directly I advise picking a position you can already coast with both feet on the pegs and dialing in the entry switch footed. The rest will naturally come to you when you dial in that first part.
