The biggest potential issue is that the effects of using a traveler (changing boom position without affecting leech tension) is roughly halved as you move from mid-boom to end-boom sheeting. If, while sitting at the dock, you move the traveler all the way to one side and then sheet in and then, without touching the sheet, you move the traveler to the other side you will get a certain degree of arc out of the boom. If the same length traveler were at the end of the boom and you went through the same motions you can see how much less travel you get out of the traveler. Also, the distance from your traveler car to your boom tackle is far greater on end boom versus mid-boom sheeting so (depending on your purchase) you may end up with a much longer mainsheet. However, you may not if you are able to reduce the purchase (which you should be able to since your leverage is so much more). If ergonomics is a problem you can rig the traveler end boom but have the mainsheet go from the tackle forward to the gooseneck and down (or run parallel to the vang if there is one) and then aft along the cabin trunk to a cleat or clutch there. None of these are problems, just things to keep in mind. Sorry for the rambling response. Good luck.
