In summary, most airlines outsource mile selling to points.com so the purchase doesn't post as a travel purchase. LifeMiles is an exception as they do the selling themselves, so your plan would work. YMMV.
I did see that post on using Barclay Arrival points but they never mentioned anything about Capital One redemptions which is what I am most interested in.
