Edward VI would also be able to simply appropriate (or his protector would) the vast Warwick Salisbury inheritance that Edward IV had simply confiscated and divided between his brothers - it would a give the new regime vast lands to hand out to loyal supporters or would enable the new King's council to enjoy a considerable income.
That points to a literal "battle royal" for guardianship of Edward VI. His mother is long dead and he has no close male relatives
The key question is what the regime does with Edward's cousins - the York Princesses were technically illegitimate but many had questioned the validity of RIchard III's act and a key figure at the new court will be their half brother the Marquess of Dorset and their mother the Queen Dowager.
So i suspect our ten year old King will soon be betrothed to his cousin Elizabeth despite the 9 year age difference.
Interesting thought. Could his wife also be his Regent?
