The 12W7 doesn't need a large enclosure per say as much as it needs one that's deep. The mounting depth of that 12" drivers is 9 inches! My Alpine 15" Type S is only 7 inches. It requires a max of 2 cf sealed vs the W7 that only needs 1.75 cf ported.

I'll probably actually be going larger than that and end up around 2.5 cf sealed when all said and done.

I'm curious; Why are you going so far over the recommended volume for the enclosure?

So I can tune it to my car, my liking. You can always make a large enclosure smaller via stuffing, but can't really make it bigger. Plus, going with a slightly larger enclosure will help flatten the response a bit.

I'm not too concerned with the driver having a lower power handling capability due to the larger enclosure since I'm running a low powered system to begin with and won't be pushing the system that hard. Again, strictly SQ here. Not to mention that a larger enclosure will actually increase efficiency a little.
