Yes, many setups possible.
I would carefully think through what to lead back and what to put on the mast, depending on how you use the boat.
Halyards led back tend to foul in the turning block and jammer when the sail is coming down. The turning block increases resistance going up. Leading halyards back also delivers a pile of line to the cockpit. Halyards on the mast are trouble free and easy to handle (mast winch required).
Will you be shorthanded, or singlehanded, or often with a crowd on board and you the only one capable?
Will you be racing with a full crew? Using a spinnaker and pole for cruising (people used to, but Gennakers got us lazy)? Do you want somebody furiously hauling up an asymmmetrical in a whirl of flying elbows in the cockpit, or would you rather have them working at the mast?
Now to abandon the socratic method: I hate halyards led back! I can't get to them anyhow if I'm behind the wheel. And a crew gets in each others' way trying to trim vang and traveller and sheets and headsails.
Doesnt every spinnaker set or jib change or unexpected moment need somebody running for the mast anyhow, clearing or unfouling or dousing or raising?
Sailing a boat from the cockpit -- well, I can't do it.
Since you get to rig it to your needs, rig it right for you. Worth some study and consideration of goals and needs.
Topping lift: A fixed wire from masthead to boom end might be OK. If that puts the boom too low when the sail's down, make the wire a few feet short and continue it with a line through a block at the boom end, up the side of the boom to a cleat near the gooseneck. You may already have an internal route for that rig.
The topping lift is only there so the boom doesn't fall on your head unexpectedly. When sailing it needs to be loose, no forces on it at all.
