'80s Jeep Wagoneer D44 fronts are very close to RBV width (IIRC only a very slight hair wider), have a driverside pumpkin, but have leaf spring perches, making for a bit more work needed to use it with coils than would a F-150 D44... With the narrowing of the F-150 axle, it's probably a wash either way, in which case I'd use the F-150 axle because it's hi-pinion.
The TJ D44 front isn't a whole lot better than the D30 (same-size outers & knuckles, and I believe the same housing thickness).
Have you thought about a D35 from an Explorer? Sure it's not a 'solid axle', but is pretty much the same strength & reliability as one, and it bolts in.
