Customising MyCred - open to bidding

Hi. Using MyCred, I wish to have a structure in place such that members on my site can earn 50% of whatever points their referrals earn. For example: Member A brings in Member B with his affiliate link. Member A earns 0.0004 by clicking on a link. Member B also earns 0.0004 by clicking on a link. Let Member A earn 50% (0.0002) of Member B's earning without reducing Member B's earning. Expecting a favourable response. Thanks. Chris.
