They want a metal shed erected on top, but there is no way thats going to
work until the base is sorted.

Initial thoughts are to erect level formwork & top the base with a little
more concrete.

Is it going to bond OK to the exciting base, especially where it
'feathers'.? Would PVA help?

Erect shed with shims or galv.washers on fixing bolts to pack it
level. Grout it where unsupported.
I assume the shed has it's own (timber?) floor. The gradient on the
base will help water drain off of it.
