I've an idea to create a memorial post for a departed friend which
would consist of a domed metal cap on a 4"x4" post.

I had originally though of making the cap of lead but a quick google
suggest that lead "burning" is well beyond my skills & equipment
levels so I wondered if either I can work the lead "panel beater
style" to cover the top and extend down the sides for a few inches
or whether I should consider a different metal like an aluminium
alloy.

Of course I could just contract the work out to someone to do
properly but I'd like to have a go myself.

Any suggestions?

You could go with the BT solution to telegraph pole tops and use an
inverted V.

Nah, for sentimental reasons it has to be domed.
