I think so.
I present the Battle of Corbridge, 918. OTL it is between Constantin of Alba and Ragnall of Viking Northumbria, over Ealred of Bamburgh keeping/re-acquiring his lands, inconclusive, maybe Ealred gets Bamburgh back, sources unclear. Ragnall a few years later takes York and then attends a conference with Aethelstan in 924. I propose we include Owain of Strathclyde into the mix and due to his participation, the battle turns into a decisive victory over the Vikings and Ragnall, he flees, and the Strathclyders pursue and annex the Isle of Mann killing Ragnall, gaining naval dominance over the Irish Sea now(maybe?). As part of his price for help, Ealred submits to his new neighbor Owain and now we have a Cumbria from coast to coast.
We could see Sitric establishing himself in York a few years earlier, helped by the lack of Gofraid, him having died at Corbridge.
In the south, Ed the Elder is consolidating his hold over Mercia after dispossessing his niece (aelfwynn) in 918, but now has to confront a rampaging Sitric who has gone south, like in OTL, due to the disaffection of Eastern Mercia over the succession. The last four of the Five Buroughs still standing, Viking cities in Eastern Mercia/Lindsey) throw in with Sitric instead of submitting to Ed.
So we come to 920 or so, Cumbria has its OTL territory plus Mann and kinda/sorta Bamburgh(uppity vassal) stretching from the Irish Sea to the North Sea, Alba has parts of Lothian and Dunbar to border Bamburgh, and Sitric holds most of Deira, plus Lindsey and parts of Eastern Mercia, and Wessex/England(its getting there) has most of what it OTL did. Ed holds his peace conference, maybe after fighting Sitric to a draw around Leicester but it is very much not an arena for submissions but meeting of equals. Sitric marries Aethelstan's sister a few years early, and borders are set as is, so Ed can continue to stomp on rebels, while Sitric consolidates his realm and the Northern Block do the same.
In 924, Aethelstan takes over and in 926 is unable to pony up the price tag for amounderness but his neighbor Owain steps up and purchases it from its owner and expands southwards. Next year, (927) Sitric dies in York and leaves his crown to his son, Olaf Cuaran, who has been reigning in Dublin, he comes over but is quickly evicted in lightning campaign by Aethelstan who then calls a conference at a crossing of the Ribble(boundary of Cumbria) in 928, to meet with the North to discuss his recent acquisition and submission to him, being stronger, Owain and Constantin resist, but Ealred decides to switch to the Saxon side, thus starting a war.
Owain and his ally Constantin, ally with Olaf Cuaran and make common cause to restore the Status quo before Sitric's death. Aethelstan and his brother lead the combined armies of Mercia and some of Wessex(due to not having enough time to quell the dissent over the disputed succession), they meet the combined allies of Owain, Olaf Cuaran, and Constantin on the field of battle near Newburgh-on-Tyne when the allies fall upon the English before they can link up with Ealred in Bernicia/Bamburgh. The battle is a close run fight, Olaf loses two cousins, Owain and Constantin both lose a son but Aethelstan and his brother are slain and the English retreat in disarray. Ealred is defeated in battle and Bamburg is besieged by Owain, while Olaf and Constantin take York for Olaf. Owain takes Bamburgh, installs a Cumbrian noble and the status quo is restored in the North. England is in a succession crisis, Mercia breaks away from Wessex, and the Welsh return to independence during the struggle.
We can speculate from there.
