On the other hand, a Magus could dip one level into cleric and two into ninja to gain channel and ki, and can then recover about two pool points per day... or he could simply take three more levels in Magus (which gives +1 pool) and the Extra Pool feat for +2 more. So it seems to me that he doesn't really benefit from this trick.
Sure.

Having both a Ki Pool and an Arcane Pool means you could effectively have twice the amount of points to work with. You can activate your Arcane Pool abilities with Ki and you can recharge Ki. Slap on an item that boosts your total healing, like Phylactery of Positive Channeling, and you can recharge multiple Ki per burst. If you have fellow Ki users in the party, they will love you.

It is definitely a niche ability. An Eldritch Scion that dips Ninja could realistically have a Ki Pool of 4. A dip of cleric could give 6/day channel energy. Combined with the Phylactery, that is potentially 18 Ki you can recharge a day. If you are willing to spare 4 levels towards this, a 2 ninja / 2 witch (hex channeler) will net you channeling with the option of increasing the healing dice by taking extra hex feat.
