If I understand your request correctly, I think you just need to configure an IKE poicy and give it the higher priority (lower number ) than the existing policies, by that you will be sure that this policy will be used first, and by the way if the IKE policy will match only identical IKE policy at your side, so regardless the priority of this policy, it will be matched.
I was wondering if there is a way to assign a isakmp policy to a tunnel group or a crypto map but more likely to a tunnel group.Because if I modify the priority of the isakmp policy then i will influence all the vpn going through phase 1 that will potentially match first the policy with a higher priority. So at then I could en up with phase 1 settings changed for existing vpns.
