Two accounts

I'm going to try to make this a long story short. I just recently came back to the RS market a few months ago being a veteran from 2011. I tried to find any previous account I may have had on OSBot to no avail, they're most likely registered on an email that use to be associated with my gold selling site.(I don't own it anymore). I made this account and everything is going very smoothly, I got into the market here, I've earned a few feedbacks here and there, ended up getting lifetime sponsor. 

Unfortunately.. yesterday I found my account, @Maruku. Is there anyway we can merge accounts on here? Is there maybe a registration date change that can happen on this account to replicate that accounts registration? If I recall correct that is a feature on IP.B. If none of those are an option can I switch to that account (with some recovery assistance) and have Lifetime Sponsor transferred there? If proving the fact I'm the real 'Maruku' becomes an issue I can ask some old time pals like @Arctic or @RoomScape to vouch for me.
