Outlaw Star. I mean, the bad guys are literally a cabal of evil space wizards, and the main character has a gun that shoots spells. The only major incompatibility is that spelljammer ships don't have extendable arms to punch each other.
okay here is another one (and you are going to think you know it but it isn't that by itself)
a dwarven clan that lives on a ringworld around a star... they are VERY unlike other dwarves though being highly magical (artificers, wizards, sorcerers and warlocks are common, with bards and clerics being uncommon). they draw power from the star at a level close to 100% (level 2 on Kardashev scale) and use it to not only power there MASSIVE defense grid and society (that uses magic so common it make Sharn on ebberon look LOW magic) but also to power these special crystals.
they send these crystals out to other spheres... and there they choose champions to become warlock/palidens that work for these dwarves as a police/peacekeeping force...
