Different MAFs, intake tubes

DISCLAIMER: Coming from the 7MGE community, I have successfully adapted a Mustang 3.5" MAF, a Supra TT MAF, and a speed density map sensor to that engine (daily driven).
Now that I have stepped up to the 2001, the computer is less easy to "trick". I wonder if anyone has attempted to use a different MAF to account for the diameter change of a larger intake pipe.
As luck would have it I tripped over an FJ cruiser TRD intake pipe. I think it would look really nice in our engine bay. In some searching, I noticed the FJ Cruiser has a similar MAF to the 01+ GS/IS. Pending some output tests, this could be a candidate.
If anyone has attempted this, please chime in. Stay tuned!
DATA:
Stock MAF comes in around 1.5V at idle. So we will see what the FJ MAF shows at idle, once I find one.

If the engine is N/A it would take some seriously wrong AFR and a long *** time at WOT to cause any damage.
But yes a wideband would be the way to go here.
I'd also love to see the results of testing since I'd love to be able to run a 3.5" intake pipe (like the SRT -"super ripoff tech") intake.
I'm about to install the SAFCII I had lying around for years in my 02 GS430. A nice 3.5" pipe to go with it would be great - yeas I realize I can just tune it with the SAFC but a closer match would be nice.
