I'm a bit worried it may make it worse, maybe the solder will just seperate from the various pins.

It seems like you're pretty comfortable doing that, but I'd be very careful about using a heat gun on it.
I swapped the EEPROM from my damaged one into a replacement unit, but it's not for the feint of heart. There are so many tiny components nearby, and they can easily drift out of alignment from their pads.
I practiced many times on junk boards before I dove in.
To prevent the solder from separating, you can dab some flux on the pins. That should help keep the solder on the pins and pads.
Good luck.
