I don't see that it is possible.

Because it's a BROKEN network config which is NOT valid. It is
physically impossible for a subnet to be present in multiple
different shared networks without breaking IP routing rules.
The answer is that you need to get your access equipment fixed. If a
client is in a different VLAN, then the relay agent MUST also be
present on that VLAN. If the relay agent is using a GIAddr which is
on a different subnet/network then it is broken and DHCP will not
work properly.
