Suggestions for building an SLA?

I'm trying to create a simple icmp sla between two customer sites on our MPLS network. From site-A I ping sourcing the IP address of our ethernet handoff, to the customer router interface IP at site-B. Then repeat the process at site-B sourcing our IP address to the customer router interface at site-A.

Long story short, we do this instead of just pinging the A-B interfaces on our side due to a crazy bug which we have been experiencing which has been blackhole-ing our customer traffic even though our A-B has been reachable from our addresses perspective.

However, I want to repeat the process at site C, but there is no customer network hardware at site C. We hold the the gateway address to a directly connected end host. However the customer has told us that he does not want us to bounce pings off their end host as a means to detect connectivity issues.

Short of firing up an end-host of our own to sit on the same subnet, is there a better way to do this? I was testing on another switch here-- putting the VRF and gateway address on an SVI, then cross-connecting it to another port on the same switch that has a valid ip on the same subnet (but not in the vrf to avoid invalid ip issues), but that doesn't seem to work at all. Any suggestions?
