That's possible, especially if the new HC doesn't produce a recovery to at least mid table. My objection to now would be changing both SD and HC at the same time.
As far as I'm concerned, Knapper's player recruitment is not the issue. His sacking of Thorup and recruitment of Manning are why I want to see him gone. I wouldn't make any judgement re. any player on the basis of this season so far; and any negative judgements I'd make on the basis of last season would not be on any of the youngsters either.
