No, you cannot replace the AP-305 firmware to make it an IAP-305. IAP models are tied to the regulatory domain (US/RW/JP/IL) which is burned into the AP.
AP models don't have regulatory code, so can't run Instant Firmware (or rather: the radios will not come up and you will see errors and cannot login after you loaded Instant firmware on an AP model).

Subject: Difference between AP-305 and IAP-305
If I purchase AP-305 and replace the firmware, can I use it as IAP-305?
Is it necessary to replace the firmware to use AP-305 as IAP-305?
Is the hardware a common design?
