I need to be able to have a host on Network-A to be able to connect to a router on Network-C - with Network-B in the middle.

Is it possible to NAT an IP from Network-A to Network-B - then NAT the resultant Network-B IP to an IP on Network-C?

Assuming you mean NAT the source IP address then yes this is perfectly possible. You just set up your NAT translations on each router eg

Router A

ip nat inside source static

Router B

ip nat inside source static

where is NET A is NET B is NET C

BTW: It's also possible to double NAT on a single router, useful when two networks address space overlaps.
