As Star says, this can be very advantageous to shorthanded sailing and you do need to be sure that any turning blocks, cleats and winches that you mount to do so are properly backed up below. There's no appreciable increase in load per se, but using cheap blocks or padeyes can increase friction.
One possible thing you need to worry about is the reefing. If you don't run all your reefing lines back as well, now you've got a two stage operation, half from the cockpit (halyard) and half at the boom/gooseneck (reefs).
There are various arrangements for double or even single line reefing led back, but they add to the cost in terms of parts (blocks, eyes, etc) and friction. If you have no intention, budget, or space to run ALL the lines back then you may in fact be better off the leave things at the mast where you'll have access to halyard and reef lines from one location.
Always a compromise, as usual.
