Soldering is no problem, just melt and bend the leads up, then dump heat into the tab until it lifts off. Tin and wick the pads clean, then solder down the replacement.
I'd be more worried that:
1. You haven't addressed the root cause, so it's likely to blow again,
2. That looks like it used to be a potted module. In other words, "you poor SOB..."
...Fixing a potted module, while absolutely possible, is on the "heroic" side of repairs. Are you sure you can't actually find/buy a replacement, considering all the time and materials you'll spend on this repair? Almost always, such repairs are "penny wise and pound foolish".
And when you're done, you have to pot it back up, which means expensive silicone (by the looks of it) resin, and maybe a vacuum chamber to be sure. Otherwise it's just going to fail again, some time later, and much worse, due to whatever environmental contamination they were potting the thing against in the first place.
