Personally I'd ditch the Scouts entirely. But then I'm heart broken that the way I've built and used my Scouts no longer is applicable.
I'd also consider taking a naked Wolf Guard for each Long Fang pack and making sure there is a Wolf Guard in
TDA for each Grey Hunter pack. Preferably with a Combi-Weapon fitting for that unit (and one Assault Cannon or
CML).
If the Grey Hunters are on foot I'd be focusing mostly on Plasma, rather than Melta. I've typically run 5 Grey Hunter packs with a 2:3 ratio of Melta

lasma and to be honest I almost never use the Melta when on foot. Given glances are buffed, Plasma would be just fine.
Wolf Guard: 236 Points
x3 w/ PA, Bolt Pistol, Close Combat Weapon
x3 w/ TDA w/ Combi-Plasma, Power Axe
x1 w/ TDA w/ Combi-Plasma, Power Axe, CML
If you were to use the above Wolf Guard (I know, I know, we all already have them built with a ton of things that aren't Power Axes) and cutting out the Wolf Scouts and replace Meltaguns with Plasma Guns to put yourself at 227. Then three options come to my mind:
1. Grab two
TDA/
SS/
CF or
TH wielding Lone Wolves, complete with a pair of Fenrisian Wolves or
2. Drop a Chooser of the Slain and grab a
TLLC Razorback for each Long Fang pack for more firepower
3. Grab two Land Speeder Typhoons for more firepower and use the remaining points on something (maybe a small pack of Fenrisian Wolves if you cut some of the fat of the Rune Priests).
Space Wolves are uber-aggressive midfield fighters. They don't have the shootyness of other armies. Pretty much have to rely on vehicles to do things. Its why
Reecius' Bjorn List and others are so
MSU intensive. Cram in as many Dreadnoughts, Land Speeders, and Long Fangs as possible and fill the rest with Razorback carried Grey Hunters. You can net yourself a lot more heavy weapons that way.
