For the main
halyard that should work. A Cunningham will be needed to tension the luff once the sail is hoisted. Assume you are bringing the
halyard back to the
cockpit which is why you're contemplating blocks and clutches. You may need a
winch to get the scallops out of a hank on
jib when the
wind pipes up. A Cunningham, tackle on the halyard or a two part tackle halyard could be used to get the tension that may be needed on the
jib.
I wouldn't encourage you to run the jib halyard back to the
cockpit unless you will always be sailing with a crew. Seems like the halyard always hangs up at the worst times when lowering/raising the jib. Running from the bow to the cockpit and back a few times isn't fun in rough seas on a small boat. Actually on any boat.
