[Game of Thrones] What difference would the Lannister army have made in the battle against the Wights and White Walkers?

Cersei puts down the wine and realises they all might die, finally sending her armies north to support Winterfell.

Bonus round 1: All the Seven Kingdoms of Westeros unite and ralliy at Winterfell/The North, bringing supplies and food from the South

Bonus round 2: The Free Cities of Essos, realising they might be next, try to play damage control in Westeros and help stop the undead invasion at Winterfell along with the united Seven Kingdoms. Night King doesn't fall for Bran's trap, can the Westeros-Essos coalition win on numbers alone?

Considering the military feats Team Cersei pulled off in Season 7? 

>!Instead of a dumb frontal charge like the Dothraki, the Golden Company cavalry goes on a deep flank and assassinates all the White Walker lieutenants watching from afar. Euron shows up with the Ironborn carrying the Iron Fleet ships 200 miles inland where they spit jets of Wildfire Byzantine-style, consuming the Dead in a green flame. When the Night King arrives on Viserion, Qyburn launches Gregor out of a trebuchet and he cleaves Viserion clean in two with a giant Valyrian steel greatsword forged from Red Rain, Nightfall, and Lady Forlorn. The Night King falls hundreds of feet and does a superhero landing, but he turns around and Euron lops his head off with a giant Valyrian axe. Then Euron pulls the Night King's pants down and mocks the size of his member.
