Another 'getting the miles' option is to have Aunt Mary pass away and have it put in the will that you get her 500,000 unused miles on AA. Transfered miles (as you note from your future wife) are included in the MM level!
It sounds like you are EXP already so the only 'thing' you are gaining is the 4 extra eVIPs. Lifetime GLD would be a step down! EXPs get First checkin and better lounge access compared to GLD.
While not 4 .. you could garner 2 additional eVIPs by hitting the 125,000 miles or points during 2006 for the 25th Anniversary Special

I have not used Coupon Connection so cannot vouch for trading of things.. tho here in the US an eVIP is sometimes valued at a 25,000mile award.
Lets see what others have to say.
