It should work. On the PIX, set up a crypto dynamic map with the transform set, and import that into your crypto map with a high policy number. If you are using preshared keys, set up an isakmp key on the PIX; if you know the range of IP addresses that might be assigned, you can use the appropriate netmask; otherwise you'll have to use the 0.0.0.0 0.0.0.0 address on the isakmp key.
