This would work but..
A knot can reduce the strength of a line by up to 50%. The worst
knots have sharp bends in the line which weakens it. (When a line is
curved, all the load is carried on the outer part of the curve and
none on the inner.)
A larks head like you describe would have a very sharp bend right
where the line enters.. very bad.
Q powerline is normally tied with an overhand knot over a double
line which has more gradual bends so it is stronger. Then after this
knot two lines go to a larkshead and the load on the larks head is
shared by both so it is twice as strong.
Hope this makes sense.
