shared-network question

I'm working with a situation where there are 2 physically separate
networks each with their own DHCP server. One is for IPTV Set-top boxes
and the other is for customer Internet use.
Due to some subscriber equipment limitations at one location, we are
needing to merge these two networks on the same physical wire.
So, the customer facing interface has multiple IP addresses assigned. I
can specify multiple 'ip-helper' addresses and I would like to keep the
DHCP servers separate still.
So, my question is, can I use a shared-network statement on each server
containing both subnets, but only allocate addresses for the Internet
network from 1 server and the Set-top boxes from the other server by
simply not putting a range statement in the subnet that I don't want to
serve addresses for on each server?
