Re: 2 IPs on 1 Interface

best is to do it through policy nat as you indicated, assume your source/inside is,if other end of tunnel wants you to come in NATed as then you need the policy nat and appropriate acls for interesting traffic.

Something similar as the exmaple link bellow.

access-list new extended permit ip

access-list policy-nat extended permit ip

static (inside,outside) access-list policy-nat

plus the cryptop map statements etc..

bellow is a link with good example , this link pertains to when you have overlaping networks between tunnels but the principle is almost the same.
