IIRC, the Pack Leader was built-in to the unit and had the same statline as the rest of the pack but an extra attack and an option to take a power sword, power fist, or power axe. On top of that, you could then add or replace the pack leader with a Wolf Guard Pack Leader who also had an extra attack but an additional point of leadership, on top of even more weapon options (like a combi-weapon and frost weapons in addition to the normal special melee weapons). So you could have a 5-man pack with a PL, a 5-man pack with a WGPL and no PL, or a 6-man+ pack with both a PL and WGPL. Just adding that into the mix would be awesome. A Space Wolves Intercessor squad with six+ marines, two of them with Thunder Hammers or Power Fists, would be very fluffy and good, making them feel a lot more like Grey Hunters of yore. And just including a Pack Leader rather than a "sergeant" is so fluffy to me: the natural alpha of that group of inductees.
