It’s going to be hard enough to get the UK to turn him over. The first set of charges were crafted to avoid Espionage Act material, but blundered into a field – computer crimes – which have been hit and miss in English courts. As I recall, Theresa May (now Prime Minister, if not for much longer) personally quashed one or two high profile hacker extraditions when she was Home Secretary.
And these are plain political charges! The UK is still in the EU and will domesticate EU law upon brexit. Judges are often comically out of touch, bet they do like to make clear their independence from the government.
