Linking Passport to Primavera through Citrix

Hope somebody can help. We currently run Primavera v5 through a Citrix server. All of our site projects are in Primavera, however, our maintenance schedule and routines are managed through Microsoft Project due to the tie-in that exists between MSP and Passport.
I would like to look at the possibility of connecting Primavera with Passport to eliminate the need for MSP.
Has anyone heard of any software/dealt with this kind of situation before?
Any feedback or help would be greatly appreciated
