Multiple Scopes for a Single Subnet

Hello All,
I have a question about DHCP scopes. If I were to set up two scopes for
the same subnet on the same server, one ranging the first half of the subnet
and the second the other half, will the server load balance the assigned ip
addresses from both scopes?
Here's my situation. I'm having tons of trouble with my users losing
connections, especially VPN, and I believe it's do to the fact that my
router has two DSL links that it load balances. I'd like to set up one of
the DSL links on a second router but would still like to use both DSLs. If I
had two scopes I could set Router A as the primary gateway for Scope 1 and
Router B as the primary for scope 2, each using the other as a secondary.
The problem is I don't have enough none production machines to test the
idea and with the state of documentation these days, no hope of finding the
answer there.

Has anyone ever tried this? How bad was it?
