Whenever we hear someone is going to "replace" such servers,
many of us strongly urge you UPGRADE instead and keep it
simple.

There is no reason it should cause any problems.

Normally DNS is NOT setup to use NLB or Clustering
since DNS servers mostly do that based on the way clients
use the DNS.

DHCP does NOT deal well with NLB either; it really needs
clustering.

Since clustering is on a PER APPLICATION basis (unlike
NLB which is per node) this works out even if DNS is on
the same box with the DHCP server.

Is Active Directory involved in any of this?
