No but yes
You can not buy two seats in your name. And a normal second ticket will be cancelled on boarding as you can not scan two BPs on board.
But there is a construct call EXTRASEAT and you will get double your standard bag allowance, including bag allowance (but not PQPs) with an extra seat to boot The wiki has more details
Normally the suggestions is consider UPS as easier and generally cheaper solution. But at today's ticket prices, it may not. But handling up to 6 bags at the airports will be awkward.
