Those each have a different bend too. The 410 is 60 degree and the 630 is 90 degree. Look at the Victory hooks, they have some hooks that will likely work. As Fatman said, you get extra flash, but that never stopped me from using hooks, not made for the mold. The shank lengths IMO may be where you'll see bigger dimensional differences. Both of those hooks have rather long shanks, so you may have to settle for a hook with shorter shank length when going with lighter wire.
If you won't be using the heavier wire hooks at all or very little in the molds, you can fix some of the flash issue with high temp silicone, using it to fill the space. Permatex makes one that I had found in an auto parts store that is good up to around 700 degree's of intermittent heat. I've had to re-do a mold once, as it's not permanent, and I've poured hundreds of jigs before the silicone started to come out. Easy to do and I don't want to make permanent changes to a mold anyway in most cases.
