No support. There's enough RNG involved with WWs; they don't need more.
I'm with Bluesette. If I get an ugly WW with a new pattern, I'm really not interested in spending a load of time (and potentially funds) trying to breed that pattern onto a nice looking wolf (or two unrelated wolves, if I want a breeding pair!). I'd much rather just level the wolf, release it, and be like "Oh, well. Better luck next time."
And if RNG did give me a WW with colours I loved, along with the new pattern, I could play around in the demo and find that I prefer a non-exclusive pattern on it, instead.
Personally, this wouldn't make me find WWs any more special than they already are. If anything, I would just find it irritating, as I like to make G1 breeding pairs. Getting two WWs with a good colour range is one thing, but getting two WWs with a good colour range AND both with the new pattern that ALSO happens to suit them well?! That doesn't sound like a fun time, to me. lol
