Are gloves of Enlarge Weapon (Complete Scoundrel p97) for my half-giant possible and legal by RAW?
With powerful build I already have a large weapon, and I'm looking to get huge sized weapon damage. I want to stay away from sizing or other similar weapon enhancements because the penalties aren't worth it to me, as I'd have to waste a feat or get strongarm bracers on top.
I must also mention my DM said I'd have to find a blacksmith who actually can make huge sized weapons, which can be very limiting… with this item basically all weapons I wield would always be one size larger, which could arguably be game-breaking although I'd say my damage is more based on power attack anyway…but extra dice are always welcome.

A use-activated or continuous version of enlarge weapon on an item would cost, according to the guidelines, 48,000 gp. The largest possible gain for going from a large weapon to a huge weapon is for a bastard sword or similar, which goes from 2d8 to 3d8, a gain of +1d8, or on average +4½. For the overwhelming majority of weapons, it is a gain of a +1d6, or on average +3½.
You can gain far more than 3-5 damage for 48k gp. Even simply adding corrosive flaming frost shocking to a +1 weapon (costing the same 48k gp) would add +4d6, for an average of +14. Roughly four times the damage, and just throwing energy properties on a weapon isn't exactly optimal.
So no, I do not think your proposed gloves of enlarge weapon are a good solution here at all. Size increases are very slow to increase damage, and are rarely the best way to do so.
