LVTTL arbiter in PCI



HI all,
We are using a PCI bridge (2.2 PCI compliant) that integrates a PCI arbiter implemented on configurable multi purpose pins.
Tha problem is that the configurable pins are not PCI compliant, but regular LVTTL pins.
 
I know that REQ* and GNT* are unidirectional and point to point signals, but it is also true that the DC characteristics are quite different and the PCI buffers are CMOS.
 
So, Is It possible to connect the 2 different buffers?
 
THANKS and regards
 
Stefano
