Is it possible to use VRRP with 2 different interfaces on the same router? The hope is to use 1 4451-X with 2 interfaces going to a switch stack so that if a link fails the VRRP will allow the traffic to use the other interface elsewhere in the stack.

You can use SVI IP address instead.

You can create a separate VRF for each interface & create the VRRP groups as needed. This is a *very* basic example & just off the top of my head.
Ex:
vrf definition Site1
address-family ipv4
!
vrf definition Site2
address-family ipv4
!
interface Gig0/0/1
vrf forwarding Site1
ip address 192.168.1.2 255.255.255.0
vrrp 1 ip 192.168.1.1
vrrp 1 priority 110
!
interface Gig0/0/2
vrf forwarding Site2
ip address 192.168.1.3 255.255.255.0
vrrp 1 ip 192.168.1.1

Hello!
As other noted you should use port-channel. Using two L3 interfaces you will have to setup routing and wont be able to use them both at the same time.

Stack can have two port in two different SW within same PortChannel
And hence you can config ISR portchannel using two interface with mode ON toward two different SW of stack.
I Prefer make it L3 portchannel not l2 and config SVI

As others have already noted, using a Etherchannel (MEC on the switch side) would normally be the preferred approach.
Many Cisco ISRs supported a manual Etherchannel but I recall (?) reading, on these forums, later ISRs might now support LACP.
