My guess is almost everyone here will tell you not to because why pay the extra 0.15% when you could simply do it on your own.
But, sure, go ahead. If you wouldn't TLH otherwise, it's a win. The big caveat, however, is that the strategy only works if you're continually making purchases. If you harvest losses and lower your basis, eventually you'll stop having losses. You need to keep purchasing stock with at higher basis so that you'll be able to capture losses. If you're still growing your wealth this should be no problem. When you retire you'll probably want to put your money elsewhere.
