I can't answer this, but I can enhance
fsa_ea's report a little. Two account holders in my household were each able to buy 50,000 miles, buy another 50,000 miles for each other ("gift") and transfer 50,000 miles to each other ("share"). Each transaction generated 50,000 bonus miles, resulting in a net balance increase of 250,000 miles for each account.
Cost: 6,630 USD for 500,000 miles (bought +300,000; bonus +300,000; transferred -100,000). Cost per mile: approx. 1.326 cents.
Your method would get the cost down to just under 6,347 USD or approx. 1.269 cents per mile, so it's worth considering. The 'simple' method, on the other hand, has the advantages of only requiring two accounts (rather than six!) and being quite unambiguously within the T&C of the promotion.
