Yes you can. No you shouldn't.
The standard blow off valve does the job that blow off valves were designed to do fine, it dumps the compressed air from the turbo back to the intake side on closed throttle.
the only reason to replace the standard valve is so you can spend a couple hundred dollars to get a noise that makes most people think you're a tool.
The other reason for not getting an atmospheric vented valve on the AFM engine is that they tend to also open when the engine is under vacuum meaning you will be adding unfiltered and unmetered air to the engine. This is far from a good thing and one of the most common causes I see on the MR2 forums for people complaining about rough running stalling etc.
Now I admit I am running a gay GFB atmo venting blow off valve on my 3S but there are a couple of mitigating circumstances here, the valve came with the intercooler I used and my engine is MAP sensed.
