Hav you ever heard of Trillian or IM2?

These are Multi-Client Messengers

They can connect to AIM, Yahoo, ICQ, MSN and IRC

Trillian offer a Pro (pay for software) and Basic version (free software)

Whereas IM2 is free

I find IM2 to be the better client however the latest official release (1.5 at time of writing {1.5.9b public released beta build also} )
has some bugs with it I suggest waiting a short time untill 1.6 is released and their skin section is online.
If you like the Skin MSN Messenger has, they used to have a MSN style skin for it.

You can still download 1.4 and download the MSN-Style skin.


But as Lopardo stated, i am sure this would be an almost impossible task for MSN Messenger to handle.

for one thing you would have to re-code the display picture to a different size because AIM buddy icons are not 96 x 96

This would be a collosal task, the closet thing available other than the multi-client messengers is the MS Outlook addon that AOL released the other week allowing you to send AIM messages to contacts in your list associated with an AIM address.
