Slugs typically shoot better with what FX calls a heavy liner. They have a slower twist rate. However, you might get lucky and find a lightweight slug that works in the standard Smooth twist X liner. Liners are inexpensive compared to a solid barrel, and easily swappable.
The FX Hybrid slug is 22g and might work, ZAN, HN, and NSA all make lightweight slugs as well. I’d stick to 23g or less and tune for 900 - 1000 fps.
So the short answer is yes you can use the same platform to shoot both pellets at 20 FPE and slugs at 40 FPE. However in all of my years, Ive come to the conclusion that I like to set one platform up for a specific projectile and leave it that way.

This seems like a perfect time to ask
Is a 1:16 twist rate slower or faster than a 1:24?
My reasoning concludes that if a 1:16 has a twist of 1 full turn in 16 inches and a 1:24 has a full turn in 24 inches
That would make the 1:16 a faster twist.
How wrong can I be?

I should respectfully clear this up.
You stated
"Slugs typically shoot better with what FX calls a heavy liner. They have a slower twist rate."
The quote is not true. Slug liners typically have ~1:16 twist which is faster than a pellet liner which in FX liners would be 1:24 or close to it, which is slower.
One full revolution of a pellet in 16 inches is a faster twist than one turn in 24".
There is some confusion because a lot, if not most, of manufacturers use faster twists in their pellet rifles than FX. Those twists are usually somewhere in the 1:18 range, which is why some of them shoot slugs well.
Since pellets are drag stabilized (as opposed to spin stabilized, like bullets), they don't need to spin fast, that is why FX has gone to slow twist in pellet liners, EXCEPT in .177 which is ~1:18, and they don't make a slug liner for .177, because there is no need. Just like round balls in muzzleloaders, pellets are more accurate and buck wind better with a little spin, but it just doesn't take much. As I said above, EXCEPT 177 which is a funny animal, lighter pellets do require more spin to stabilize, hence the ~1-17" twist being so popular.
