Comparing Room-only rack rates for a trip in early November (5 nights, Fri-Wed) for 2 adults, 1 child (3 y/o):
Portofino Bay - Garden View, 2 Queen room: $249/night, $1,400.64 total
Wilderness Lodge - Standard, Woods view, 2 Queen room: $381.60 avg/night, $2,146.51 total
Wilderness Lodge was the cheapest WDW Deluxe to compare to. The avg/night rate for the next lowest priced WDW Deluxe was AKL at $454.40 avg/night, and it only goes up from there.
I really don't think Disney has the room to increase their Deluxe hotel rack rates to include what they'd need to include to cover a paid express pass type option.
*Note: I did this comparison using rack rates. I'm aware that there are discounts that can make those lower - probably at both WDW and Universal resorts, but those are variables. I was trying to keep the comparison as consistent as possible.*
