Yes, Our 4.9 is running on the 730 ecm, it does not have electronic trans capabilites so we are running with a 4T60. The sensors are the same, idle is different then caddy, you will need an IAC instead. Rockcrawl origninally set his up this way before more work was done on the caddy ecm. Here is a pic of Rockcrawls engine with the set up you may be thinking about.
If you check out his web site you will find more info. Including the custom PROM required to run the 4.9 on a 730 ecm www.fieroaddiction.com
